Rotating speed of dc motor controller by analysis

by:Hoprio     2020-08-01
Dc motor controller in the job, will encounter this or that kind of reasons, led to the decrease of the rotational speed, once a drop in speed will affect the operation efficiency of motor controller, so we should take corresponding solutions according to reason. 1. Cage rotor broken bar. If the screen cage rotor broken bars phenomenon, then in the operation of the stator current meter pointer will be back and forth, sometimes sparks fly out from within, and hum. Break the need to adopt a detector or iron powder method to find the article break fault, and take the corresponding repair measures. 2. Low voltage power supply. Check the voltage of the dc motor controller input, determine the power supply voltage is too low, adjust the power supply voltage. 3. The stator winding of motor controller connection errors. In general, the connection mode of the stator winding as the D shape, if the mistake form Y connection you need in a timely manner to correct. The above is the controller of dc motor speed decline phenomenon is introduced and the processing, hope to help everyone.
