Rotating speed of dc motor controller down processing measures

by:Hoprio     2020-08-02
At work, dc motor controller sometimes due to various reasons led to the decrease of the rotational speed. Speed decreases once will influence the running efficiency of the motor controller, so we should take timely corresponding solution for reasonable operation. Below small make up teach you what the speed decrease. 1. Cage rotor broken bar: if it's cage rotor broken bar, so in the operation of the motor controller in the stator current meter pointer will swing back and forth, sometimes sparks will fly out from inside the explosion-proof motor controller, and hum. At this time, we need to use fault detector or iron powder method to find the article break fault, and take the corresponding repair measures. 2. Low voltage power supply, through to the voltage of the dc motor controller input checking, wait to make sure supply voltage is too low, adjust the power supply voltage. Above is to meet the fall speed of processing, you know?
