Dc motor controller and ac motor controller of three big difference

by:Hoprio     2020-08-01
Today we are going to learn about the difference between dc motor controller and ac motor controller. 1. External power supply: dc motor controller chooses direct current for power supply, and choose an alternating current for power supply ac motor controller. 2. Structure: the principle of dc motor controller is relatively simple, complicated structure, bad for maintenance; The principle of ac motor controller is complex, but the structure is simple, easy to maintain. 3. Speed: dc motor controller without other device to cooperate, can achieve smooth and economical speed; Complete control of motor speed and ac motor controller cannot themselves, need a frequency conversion device. That is the difference, you know?
