cell phone jammer consists of the following parts

cell phone jammer  consists of the following parts.
However, the drawback of CMOS is too prone to noise, this is mainly because of the early design of the CMOS when dealing with rapidly changing images, due to current changes too often will produce overheating. CCD and CMOS respective advantages and disadvantages, from a technical perspective we can compare the two main difference between: information access in different ways. CCD sensor the charge stored in the information required under the control of the synchronization signal the implementation of the transfer of a one to read the charge transfer of information and reading the output need to have a clock control circuit and power to match the entire circuit is more complex. CMOS sensor to generate direct current (or voltage) signal after photoelectric conversion signal read is very simple. The input voltage of  cell phone jammer  is 110—240V.
Speed differences. CCD sensor needs under the control of the synchronization clock to the output of the behavioral unit of a one slow; CMOS sensors capture light signals at the same time you can remove the signal, but also deal with the image information of each unit, the speed much faster than CCD. Power supply and power consumption. CCD sensor CCD are mostly three sets of power supply and large power consumption; CMOS sensor only needs to use a power supply, power consumption is very small, only the CCD Charge Coupled Device 1/8 to 1/10, the CMOS photoelectric sensor energy efficiency has a great advantage. Image quality. CCD sensor production technology started earlier, the technology is relatively mature. There is a working indication light on the panel of  cell phone jammer .
The PN combined with silicon dioxide isolation layer isolating noise, the image quality is relatively CMOS sensor has certain advantages. The high integration of the CMOS sensor, photoelectric sensor and circuit are very close to the optical, electrical and magnetic interference between the more serious noise impact on image quality. In the same resolution, CMOS prices cheaper than CCD, but lower image quality compared to CCD CMOS devices. So far, the market, the vast majority of consumer level and high-end digital cameras use CCD sensors; CMOS sensor as a low-end products used in the camera head. Whether the CCD sensor and became one of the people to judge the standard of digital cameras grade. The red indication light of cell phone jammer  shows that cell phone jammer  works normally.
MIDI (Musical Instrument Digital Interface, Musical Instrument Digital Interface) is a unified exchange agreement between an electronic musical instruments and electronic instruments and computer. Come out from the early 1980s has now become synonymous with computer music. MIDI files are not like WAV or MP3, as quantified record the sound of music every time change, it is just a description of the "musical language", as long as want to play music statements down on it, that record each sound sounds, musical alphabet, loudness, angle, time to check sound library, according to records should be sent sound simple to say that each track corresponds to a musical instrument, above a specific format to record the music played in every moment of the instrument .

It is unnecessary for the customer to select cell phone jammer

If the needed shielding range is very big, it can be realized by installing several  cell phone jammer .
For example, in a moment is defined as the piano track record of the above mentioned 1,3,5 consisting of chords, then the chip query the sound library to get the corresponding audio, and then synthesis, play. The space occupied by these information is very small, up to tens of K, is very suitable for such occasions with a small storage space for mobile phone (different formats polyphonic ringtones only increased a number of special effects or encrypted information, in essence, is actually a MIDI file). Phone record music with MIDI in the same or similar. Recorded in the whole tone, and complex chords sound record. That being the case, why our mobile phones is still so appealing? Since I can not press the piano, "135". cell phone jammer  runs stably in the practical use in central government agency secrecy units and state agency secrecy units.
Then three piano according to 1,3,5 not to be the fact the phone chord precisely this way to achieve this chord, although not as good as the real chords nice, but the release from the cell phone out of it almost like genuine a. This chords on an instrument n instrument mono process, known as the "chord decomposition. Just look at the MIDI editing software can be found, one which is often a lot of the same sound tracks, each track is mono. Ringtones can be broadly divided into monosyllabic ring tones, three chords, chords, 16 chords, 32 chords, 40 chords, 64 chord such as ringtones. Phone 16 polyphonic 32 polyphonic 40 chord "," 64 chord ". HTCX-100A is the small-type directional  cell phone jammer .
In fact, refers to the "polyphony". The precise definition should be 16 polyphonic ring tones, 32 polyphonic ringtones. The so-called "polyphony" refers to the number of MIDI music can be issued at the same time sound. Monophonic and polyphonic ring tones sound quite different; four polyphonic ringtones and 16 polyphonic sound too single book, the difference is relatively large, 40 polyphonic and 32 polyphonic ringtones difference is not big, and 64 polyphonic and 40 polyphonic difference is big. In short, three-chord, four chord is a grade; 16 chord is a grade; 32 polyphonic 40 chord is a grade; 64 chord is a grade. The mainstream polyphonic cell phone In addition to support the MIDI format, but also their respective support a variety of other audio formats such as WAV, MMF, MP3 and other. 2 outdoor warfield-type directional  cell phone jammer  should be adopted.
Have different characteristics and backgrounds of these audio formats: WAV: WAV (Waveform Audio), WAVE file extension resource format is Microsoft's audio information stored on the Windows platform. WAVE is one of the stored digitized voice data file format on the PC. Produced by the common CD player is digital sampling technology, just not documented. Therefore, WAV audio sound quality is comparable with CD quality. WAV format audio that comes with Windows Media Player to play it. means the specific installation position of  cell phone jammer .It is unnecessary for the customer to select cell phone jammer

Speaker sound chamber must be closed directly with the speaker and the shell between the speaker and the shell must be affixed to the annular foam closed, speaker side shell long ring circumference bone surrounded by unilateral clearance stay 0.1mm. If the speaker and the shell separated antenna bracket, between the speaker and the antenna bracket must be affixed to the ring foam closure, between the antenna bracket shell must also be affixed to the annular foam closed. In short, the sound of the speakers through the sound hole on the shell to spread out the front speakers sound chamber height should be greater than 1.5mm. speakers sound cavity height is the vertical distance refers to the front of the speaker to the housing wall, in order to ensure adequate speakers sound chamber height, and can even make the inside of the shell the sound chamber thick plastic to dig thin 0.6mm. It is the research and development ability of  Cell Phone Jammers .
The sound hole area must reach 15% of the speakers the sound, the sound hole area is the total area of the sound hole. Speaker the sound area is to remove the foam in the middle part of the area of the speaker positive, the height of the sound chamber of the speaker The higher the requirements the greater the proportion of the sound hole area accounted for speaker sound area, when the horn sound chamber height of more than 20, the sound hole area and speaker sound area that is 100% with most phones in terms of speaker sound chamber in the 1.5 ~ 4mm, and the sound hole area accounted for speaker sound area of 15% to 20%, better sound effects. out the structure of the sound hole is the most simple approach is to directly on the shell openings hole array, it can be a head of strip hole. Generally, good process generates the good product of  Cell Phone Jammers .
In order to prevent dust and foreign matter into the sound chamber, can be affixed inside the enclosure dust network, for the beautiful, the sound hole on the outside can be affixed to the nickel plate, PC tablets, and other decorative pieces, small mesh diameter of the nickel plate 0.3mm, nickel plate, inside the enclosure can not affixed to the dust network. speaker after tune the low frequency part of the main impact of ringtones, high frequency part is smaller, you can not do the requirements. In order to get good bass, no component interference on the motherboard, you can use the antenna bracket and motherboard with affixed foam speaker Tune closed after the formation of the sound chamber in order to get more awesome bass vibration effects, speakers, family speaker. The second way is the technology review of  Cell Phone Jammers .
According to the size of the sound vibration horn can produce different strength of the shock, vibration directly transmitted through the shell of the user's hands.

The company selects a local supplier of Cell Phone Jammers finally

The company selects a local supplier of Cell Phone Jammers finally.
End-user perceived service performance data will determine the merits of the device. Thus, in the 3G era, the focus is shifting test. Although the assessment of the minimum performance mobile and protocol conformance testing is always important, but more and more focus on the verification test will end support on applications and other advanced features. Run-time performance of some applications often directly affect the end user experience, so in order to achieve the success of new services and applications deployed before the deployment test tools to help manufacturers and operators to end applications in the laboratory to determine the existence of problem, the test environment must be in the mobile phone sales to end-users before it, including integration, design verification, interoperability and application service testing, including a comprehensive assessment. The local supplier of Cell Phone Jammers provides lots of Cell Phone Jammers of high quality.
Currently, the network can also be used to simulate the terminal conformance testing. Live network testing is mainly based on the current network of services to achieve the corresponding test in the existing network equipment, network configuration, and network support business functions in the conduct of the test; while the analog network is concerned, the current network does not support some of the performance test is to protect the future network equipment to upgrade or add new services or network structure evolution was able to ensure the terminal to work properly. It is more convenient for the company to choose the local supplier of Cell Phone Jammers .
Test for smart phones, set up a test environment often also requires a lot of peripheral equipment and funds. In the process of building a test environment, the need to consider specific testing process, early unit testing, integration testing, demand is relatively independent of knowledge of testing tools and test engineers require higher skills, such as test scripting, maintenance, and automated testing building. The latter part of system testing, acceptance testing process, the application of numerous and complicated business, the vast majority of cases, can make use of existing network services environment. However, taking into account the needs of different types of tests, test engineers still need to prepare a one-time investment in equipment, perform tests to ensure the effectiveness and adequacy. Module and the corresponding input of the test environment at least as shown in Table 5.1. The quotation price of Cell Phone Jammers of the local supplier is lower than that of others.Specific functions and typical business processes as follows: point to point business processes: this site MO and MT between the sending and receiving processes; different places and Ben Wang MO MT network flow between the transceiver; Benwang MO MT network between the transceiver and the remote process; point of SP business processes: this site end-user access to remote SP; remote end-user SP visits Ben Wang; notification alarm business processes: sub-terminal message storage space is available and whether the terminal and the two cases. SMS storage capacity is full or out of service on or off the user can not send and receive text messages process.

The material test of Cell Phone Jammers cannot be cancelled

 The material test of Cell Phone Jammers cannot be cancelled.
In the case shown, the signal after the mixer through C460 anyone to FL457, FL457 selected by the 400MHz IF signal, IF signal amplified by Q480 to IF ICU200 demodulation, Q480 bias voltage of C7 by the U200 sent by SW-VCC pin provides. It should be noted: in a conversion superheterodyne receiver circuit, there is an IF amplifier; in the second conversion superheterodyne receiver is usually the first and second intermediate frequency amplifier; in linear direct conversion receiver , there is no IF amplifier. In cell phone communications and cell phone circuit, commonly used demodulation techniques are phase-locked demodulator, quadrature frequency discriminator demodulator. Phase-locked loop (PLL) tracks the input signal can also be used for demodulation. Figure 4-12 is a block diagram of a phase-locked demodulator. Motorola 928 cell phone use is the phase-locked demodulator. Phase-locked demodulator reference signal comes from a 430MHz oscillator. The production task of Cell Phone Jammers of this month is very tense.
Phase detector input by phase comparison of the two signals, the output signal of a frequency modulated signal tracking, through a low pass filter to filter out high frequency noise obtained after demodulation output. Motorola, Nokia and Samsung cell phones are used in phase-locked demodulation circuit. Figure 4-13 for the orthogonal frequency discriminator block diagram. In orthogonal frequency discriminator, the phase shift network will transform the phase change of frequency changes, phase changes in the multiplier will be transformed into voltage changes. FM signal with the phase shift number multiplied by the multiplier low-pass filter output signal to filter out high frequency components, we obtain the demodulated signal. Typically, the circuit in the modern communications equipment, in addition to quadrature coil, the frequency discriminator of the other circuits are integrated on-chip. The workshop arranges three shifts to manufacture Cell Phone Jammers .
It must be noted is this: here said demodulation means to receive radio frequency circuit will contain information on RF or IF signal to restore a 67.707kHz baseband signal demodulation (for GSM cell phones). In logic there is an audio circuit GMSK demodulation, it is 67.707kHz signal to restore the digital signal. Receiver RF section of the demodulator circuit output is the baseband signal receiver, the signal of the center frequency of 67.707kHz. The director is in charge of manufacture supervision of Cell Phone Jammers .

The warehouse of Cell Phone Jammers has been put into service

The dispatcher has arranged the working table of manufacturing Cell Phone Jammers .
As the user capacity, a larger number of base stations, generally does not exist a wide range of signal blind area, the repeater is used to solve a small area of fill signal blind and building coverage. Fiber to the building is not yet universal in the case, requires the use of wireless repeaters. As the building increases, the number of repeaters required will also increase, there will be a base station to configure multiple repeater situation. However, the introduction of the repeater station is bound to interfere, the interference will increase with the increasing number of repeaters, especially the introduction of high-power repeater, system interference will significantly increase. Thus, in dense urban areas should be using low-power (1W or less) repeater. The dispatcher added 2 more workers to the night shift of Cell Phone Jammers .
User Part (UP): responsible for producing and receiving signaling information of different business users, some users can be divided into phone users (TUP), circuit switched data users (DUP), N-ISDN user (ISUP) and mobile phone users (MTUP ) and so on. No. Signaling System 7 4 hierarchy system with 7-layer OSI model, the corresponding relationship shown in Figure 3. The right half of the figure in 1980's No. 4 Structure Signaling System 7, its main function is to control the call connection establishment and release, it supports only the information related with the call connection; left part of the new structure introduced in 1988, nothing can be sent with the call connection information, to adapt to the development of communication networks. Level 1: MTP level 1 for the signaling data link level, the first layer of the OSI model physical layer. Signaling data link is 64 kbit / s bi-directional channel, the digital option to group-level semi-fixed terminal connected to the signal.
 Moreover, the support of the majority of smart phone operating systems are using Intel embedded processors, a relatively high frequency, in addition, the use of the smart phone operating system, other hardware configurations (such as memory, memory card capacity, etc.) are more used other operating system for smart phones to be much higher, so the relatively strong performance, it speeds up the operation. However, this series of cell phones also have some disadvantages, such as the high because of the configuration, multi-function resulting from power consumption, battery life is short, high-cost hardware shortcomings. Family of operating systems including Windows Mobile SmartPhone and Pocket PC Phone both platforms. Pocket PC phone is mainly used for PDA-type smart phone, SmartPhone is mainly single-handed smartphone operating system.  The new building of the warehouse of Cell Phone Jammers has been put into service.
PALM is 3Com's Palm Computing Division developed a 32-bit embedded operating system, originally a manufacturer of Pocket PC and Pocket PC operating system-based company, PALM PALM smartphone operating system used and used with the PALM PDA The operating system is very similar, therefore, based on the operating system for cell phones has more third-party software, has previously used the PALM handheld computer users to very quickly grasp the kind of smart phones. As the PALM has followed Less is More (less is more) this concept to design, so, with the launch of Microsoft's operating system to occupy a large amount of system resources and storage capacity is different is that it is itself a very small share of memory, based on PALM written application operating system share a small space, usually only a few dozen KB, so the operating system based on Pocket PC PALM Although only a few megabytes of memory but you can run many applications.

The coherent photons within the volume of degeneracy four kinds of meaning: the four-photon degeneracy of the meaning of the photon number, in the same relative number of photons inside. (2) spontaneous emission: emitted by the atomic spontaneous transition phenomenon of light. Spontaneous emission: spontaneous emission (3) stimulated absorption transition: in the low-energy state E1 of an atom at a frequency of ν role of the radiation field (excitation), the stimulated absorption transitions: stimulated absorption transition energy of photons absorbed to a certain energy state E2 transition process. (4) stimulated emission and stimulated emission transitions: stimulated absorption of the anti-transition process is stimulated emission transition. The latest Cell Phone Jammers can remote control the computer and write letters on the wall as well.Can be stimulated in the stimulated emission of radiation and transitions: stimulated emission and stimulated emission class E2 transition frequency v of the atoms in the radiation field, the transition to a low-energy state E1 and radiation photon energy hv. Stimulated radiative transition into light waves emitted by the stimulated emission. (5) inversion: in the non-thermal equilibrium, energy level is greater than the population on low-level set of populations, known as the population on the anti-inversion: the number of anti-particles around (inversion). (6) self-oscillation conditions: small signal gain coefficient g0 loss greater than or equal to include amplifiers and cavity loss in the self-excited oscillation conditions: self-oscillation conditions the average loss factor α (7) The main characteristics of the laser: spatial coherence and direction, temporal coherence and monochromaticity, high brightness (strong coherent laser main features: the main characteristics of laser light) 3.To choose a perfect Cell Phone Jammers people should firstly check out by its appearance. In order to make helium-neon laser coherence length of 1KM, it should be the number of monochromatic ? Solution: Let the coherence time τ, then the coherence length of the speed of light and the coherence time of the product, that if the laser and maser at 10? M, 500nm and output power of 1 watt continuous, asked on the second level from the laser level down is the number of particle transitions? solution: power is the energy output per unit time, so we set out in the time dt the energy dE, then power = dE / dt laser or maser output electromagnetic energy is the Planck constant and the product, that is: dE = nhν, dt where n is the number of photons within the output, which is equivalent to the cavity photon number of excited particles in high energy radiation in the time dt transitions to low-level number (frequency between energy levels ν). The above analysis can be the following form: To determine the molecular energy levels of the spontaneous emission lifetime E4 τs4. People should choose a Cell Phone Jammers by well knowing its practical functions.

Cell Phone Jammers  has the after service of money-back guarantee.
Laser allows people to effectively use advanced methods and means unprecedented, unparalleled benefits and to get results, so as to promote the development of productivity. If microscopic particles such as atoms or molecules with high energy and low energy level E2 E1, E2 and E1 energy level populations on the number density of N2 and N1, in the two-level transition between the existence of spontaneous emission, stimulated emission and stimulated transitions absorption transition, three processes. Transitions generated by stimulated emission of light by stimulated emission, and the incident light has the same frequency, phase, propagation direction and polarization direction. Therefore, a large number of particles in the same excitation of coherent radiation field produced by the stimulated emission light is coherent. Stimulated emission transition probability and stimulated absorption transition probabilities are proportional to the incident monochromatic radiation field energy density. The money-back guarantee service of  Cell Phone Jammers  can ensure the profit of the customer to the largest extent.
When the two-level statistical weights are equal, the probability of the two processes are equal. In the case of thermal equilibrium N2 <N1, so spontaneous transitions dominate the absorption of light through the material is usually due to shock absorption and attenuation. Excitation energy can damage the outside thermal equilibrium leaving the N2> N1, this state is called population inversion. In this case, the stimulated emission transition dominant. Light through a period of length l in the inversion state of the laser working substance (active substance), the light intensity increases eGl times. G is proportional to the (N2-N1) of the coefficient, called the gain factor, and its size is also working with the nature of the material and the laser light frequency. Period of active material is a laser amplifier.  A large number of photons concentrated in a very small space within the injection, the natural high energy density.
Activation of the laser crystal used mainly for transition metal ions and trivalent ions of rare earth ions. Transition metal ions in the outer layer of the optical electrons are 3d electrons in the crystal around the optical electronics are vulnerable to the direct effect of crystal field, so different types of crystal structure, its spectral properties are very different.  Cell Phone Jammers  should be used in the places where there are no electromagnetic interference. Trivalent rare-earth ion 4f electrons by 5s and 5p outer electrons of the shielding effect, so it weakened crystal field, but the role of the crystal field perturbation have been forbidden 4f electronic transitions become possible to produce narrow-band absorption and fluorescence line.

Many customers speak highly of this kind of cell phone jammer

Many customers speak highly of this kind of cell phone jammer .
"At present, although the mobile payment pilot project carried out smoothly, but in the practical application of mobile payment is still many problems." China UnionPay product innovation, product, manager and co-director of completed space that, first of all, from a technical and safety point of view, Both operators or banks, cell phone companies or third-party payment platform, the current mobile payment function is still not enough to bring the development of a leap for the industry. "Especially in the payment function on cell phones, need e-commerce market segments, as well as the breadth of application, convenience, and so continue to strengthen cooperation, and the current fragmented approach within the industry chain is clearly contrary to this demand." Followed by In the business model, although it is imperative that mobile payment is considered payment of the revolution, but how to develop consumer payment habits, a reasonable business model is an urgent problem; combined with the current domestic industry because of the demands of the different mobile payment led to emergence of a variety of technology solutions industry and business model development of parallel state, which will definitely lead to waste of resources, can easily lead to vicious competition. The painting canvas size of cell phone jammer can be customized.
For example, according to the different carriers, the more common mobile payment solutions there are four, namely, NFC, RF-SIM, SIMPass and smart SD card, at present, China Mobile selected the RF-SIM technology, China Telecom and China Unicom selected SIMPass Technology, China UnionPay chose the smart SD card solution. In the technical standards, the parties choose vary, at present, China Cell phone payment technology solutions using the 2.4G standard, China UnionPay 13.56M Hz using NFC technology, the two camps of two different standards, so a lot of chips vendors and technical support vendor at a loss. In a difficult selection process, many manufacturers are providing solutions to promote their own to support two different standards. But the lack of industry standards, it is causing a waste of technology.  cell phone jammer can intercept the signal from the satellite because of the new technology.
For example, China Mobile selected based on 2.4GHz RF-SIM mobile payment standard, and currently the most popular mode of POS machine is not compatible 13.56M To this end, China Mobile launched dual-band 2.4G/13.56M POS terminals, but because of cost higher, is also only on a small scale pilot projects. "In fact, the user only in the layout of the shopping malls of China Mobile POS machine to use mobile payment, if other carriers want users to use mobile payments at this mall, you can only look forward to their respective operators are also laying the corresponding POS machines of this the terminal. this way will result in waste of resources, convenient for users, the operators are input costs too much. "a mobile payment business solutions provider, said. The transmitting power of cell phone jammer is 10dBm.

cell phone jammer has been produced according to the real needs

cell phone jammer  has been produced according to the real needs and actual requirements.
However, with the flat trend of the mobile phone market development and channel, the Samsung mobile phones in the fierce market competition is gradually emerging channels are difficult to overcome the disadvantaged. Threat of competitive brands, low channel cost price: this sales channel is too long, the middle of profits consume a lot of the high cost channels. The retailer's lack of enthusiasm, the driving force of the channel is weakened, it is more important is the reaction speed is not fast enough, not flexible enough, the market feedback is slow. Nokia and other brands, has taken the lead to solve this problem, the channel cost advantage. Country on behalf of their own operational drawbacks of the threat: a large network of agents in the hollow, especially the coverage of 34 cities, and management.
Samsung should now adopt a wide range of channel policies, Gome (the acquisition of Yongle), Suning, Dazhong five-star chain of home appliance business, and Di ICT, Society enjoy the large mobile phone chain stores, direct supply, skip the original National Assembly. The pattern is as follows: the direct supply of advantages: to reduce the channel level, reduce distribution costs. The original Samsung dealer mode, to the ex-factory price from the retail price of about 25% of the channel profit margins, due to the different division of labor and channel the right to not part of the space is basically a shared equally by the agent and the chain. Direct supply mode is canceled, the intermediate links, chains, direct supply, distribution costs can be reduced by about 40%. cell phone jammer  has been produced according to the real needs and actual requirements.
The new channel strategy is more effective. Further possible sales channels of distribution performance, service capabilities, maintenance costs and influence under the premise of the target market segments, through a comprehensive analysis of clear advantages and disadvantages of each channel, thus ensuring the distribution channels corresponds to a match and the characteristics of market segments, to achieve effective coverage of the regional market. To maximize the overall efficiency of the new channel. Fully considered the smooth business flow, information flow, logistics, capital flow and operational management processes and maintenance costs. New strategy to take the intensive marketing, stressed that the channel construction principle of multi-channel links.

The pulse frequency should speed up the process

 With the advent of fully digital AC servo system, AC servo motor is also increasingly used in digital control systems.
Order to adapt to the trend of development of digital control, motion control systems, most of the stepper motor, or all-digital AC servo motor as the implementation of the motor. Although both are similar in the control mode (pulse string and direction signal), but there are large differences in performance and applications. Now on both the use of performance for comparison. A control accuracy of different 45The two-phase hybrid stepping motor step angle is generally 3.6 °, 1.8 °, the five-phase hybrid stepper motor step angle of 0.72 °, 0.36 °.   the increase of the phase current decreases, resulting in decreased torque. 4. Normal operation of the stepper motor low speed, but higher than a certain speed can not be started, accompanied by howling. The stepper motor has a technical parameter: load starting frequency, stepper motor with no load to start the normal pulse frequency, pulse frequency is higher than this value, the motor does not start, you may lose steps or stall. Load case, the starting frequency should be lower. If you want the motor to achieve high-speed rotation, the pulse frequency should speed up the process,
 so completely normal appearance of stepper motor temperature is 80-90 degrees Celsius. Why torque stepper motor with the speed increases down? When the stepper motor rotates, the inductance of the motor windings of each phase will form a reverse electromotive force; the higher the frequency the greater the back EMF. In its role, the motor with the frequency (or speed),  Therefore, a receiver of a portable  cell phone jammer  can not be subjected to the control of different transmitters. the increase of the phase current decreases, resulting in decreased torque. 428 stepper motor at low speeds normal operation, but higher than a certain speed will not be able to start, accompanied by howling?
If the motor speed is higher or faster response to the request, then the voltage values are high, but note that the ripple voltage can not exceed the maximum input voltage of the drive, otherwise it may damage the drive. B. current power supply current is generally determined according to the drive output current I Linear power supply current is generally preferable to I 1.1 to 1.3 times; if the switching power supply, supply current is generally preferable to I 1.5 to 2.0 times. 13 hybrid stepper motor drive signals off-line.
There are some high-performance stepper motor step angle is smaller. EDM machine tools such as Stone produced a stepper motor, its step angle of 0.09 °; Germany one hundred Glasgow (BERGER LAHR) production of three-phase hybrid stepping motor of its step angle by The DIP switch is set to 1.8 °, 0.9 °, 0.72 °, 0.36 °, 0.18 °, 0.09 °, 0.072 °, 0.036 °, compatible with a two-phase and five-phase hybrid stepper motor step angle.
