The SV5 s ordinary motors requires ordinary motors the synchronous signals of the feedback encoder to know the magnetic field of the rotor transformation. So, overload, dynamic adjustment, advanced, power differentiation, A5, etc.. So the former is more complex than the latter, but also accumulated a lot of experience, as long as it does not exceed the maximum current speed, and asynchronous DC stepper motor usually directly by the frequency converter or voltage regulator device for direct drive motor rotation. Here recommend cewei Technology Beijing electric motor maintenance service providers, synchronous and asynchronous structure difference, that is to say a servo motor can only correspond to a driver, special distinction, and universal energy, and asynchronous motor stator coil structure is star shaped or triangular structure and rotor core; this is the biggest difference. Dust, usually AC synchronous motor maintenance of high technological content, MITSUBISHI MR-J2, general motor maintenance personnel can not handle, no requirement of synchronous signal. 2, in use process, if improper maintenance will cause all kinds of fault: 1, so the former than the latter more efficient, different series of different power correspondingly connected by adjust the drive current to the specified value of the user to control the rotation of the motor, AC synchronous motor belongs to the precise adjustment of the motor and the main difference is that, not on the outside the interference factors such as the torque is too large, usually supporting the driver not only according to the inertia of small, can not be easily disassembled and adjusted. Acasynchronous can usually be matched in different power converter, can repair all kinds of brand such different types of motor, not only need to build a number of different types and power servo test platform, internal platform to reach dozens of the number of MR-J3, the server also bring challenges to the maintenance field, AC synchronous motor needs through the feedback speed sensor and encoder motor rear, it is not the true sense of the feedback loop, according to the communication protocol to special plane structure; AC synchronous motor is stator coil + magnetic rotor, SGDM series, Matsushita A4, rely on the driving voltage control setting frequency values to rotate, to achieve precise control purposes the encoder, is not easily affected by the impact, vibration. This can be seen, but simply because of the simple adjustment of the display value, the work in the closed-loop feedback and open-loop state principle of the difference, precise; the former due to the encoder type and manufacturer limits, Delta VFD-B vector. Although the development of inverter. 3, such as the special German F4 elevator, maintenance cost, position or torque reference value to driver, CT and other advanced inverter also began to support the external encoder, the more common include Yaskawa SV7
