Rotating speed of dc motor controller by cause analysis
Dc motor controller in the work, for various reasons led to the decrease of the rotational speed, what can we do about it? Below small make up for it. 1. Low voltage power supply, the voltage of the dc motor controller input check to confirm the power supply voltage. If the voltage is too low, need to adjust the supply voltage. 2. Motor controller of the stator winding connection error: if for D shape when the normal operation of the connection of the stator winding, missed form Y connection, should be timely check the correct. To sum up, dc motor controller, speed to the cause I hope it can help you.
