  • What are the two main types of motor performance?

    What are the two main types of motor performance?

    18 May 2020

      The main performance of the motor is divided into: one is the starting performance; the other is the running performance: Starting performance: starting torque, starting current. Generally, the greater the starting torque, the better, and the ...

  • What are the operating characteristics of fuses used in motor circuits?

    What are the operating characteristics of fuses used in motor circuits?

    11 May 2020

      The action of the liming motor circuit using a fuse is realized by the fuse of the melt. When the current is large, the time required for the fuse of the melt is shorter. When the current is small, it takes a long time to melt the melt, and it...

  • What hazards may occur when the motor operating voltage exceeds the allowable range?

    What hazards may occur when the motor operating voltage exceeds the allowable range?

    27 Apr 2020

    For liming motor, the following hazards may occur when the operating voltage exceeds the allowable range: 1. When liming motor starting, the power supply voltage drops too much, the start is slow or even unable to start. For asynchronous motors, the ...

  • What are the stator components of the motor

    What are the stator components of the motor

    20 Apr 2020

      Shengzhou Liming Motor Co., Ltd. stator is mainly composed of three parts: stator core, stator winding and machine base. The role of the stator is to generate a rotating magnetic field after driving three-phase symmetrical alternating current ...

  • What is the main reason for the noise when the motor is running?

    What is the main reason for the noise when the motor is running?

    13 Apr 2020

    When the motor is running, there are three aspects of noise, one is electromagnetic noise, the other is mechanical noise, and the third is ventilation noise. 1.Electromagnetic noise. Mainly caused by the air gap harmonic magnetic field, the radial al...

  • How to adjust the speed of the motor through stator voltage regulation?

    How to adjust the speed of the motor through stator voltage regulation?

    07 Apr 2020

    When the load torque is constant, as the motor stator voltage decreases, the main magnetic flux decreases, the rotor induced electromotive force decreases, the rotor current decreases, the electromagnetic force received by the rotor decreases, the sl...

  • How can the motor be controlled by changing the pole speed?

    How can the motor be controlled by changing the pole speed?

    03 Apr 2020

      Pole-changing speed regulation is realized by changing the series-parallel relationship of the motor winding through external switch switching. Only step adjustment is possible (generally has two speeds). If the motor is switched from two pole...

  • What are the consequences of starting the motor when the phase is missing and how to deal with it?

    What are the consequences of starting the motor when the phase is missing and how to deal with it?

    28 Mar 2020

      When the aluminum shell motor is stopped, the motor is missing when a phase power supply is started. Generally, only a dull buzzing sound will be issued, and the motor will not turn. If the power is not immediately disconnected, the motor wind...
