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 ...
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...
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 ...
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 ...
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...
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...
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...
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...
