The difference between dc motor controller and ac motor controller

by:Hoprio     2020-07-18

1. Selection of power supply, dc motor controller is chosen is a dc power supply, and choose the ac power ac motor controller. 2. Of the different structure: dc motor controller with a commutator, and ac motor controller without commutator. Dc motor controller in low voltage requirements of the circuit, dc power supply, convenient to carry. 3. Presence of commutator: generally speaking, there are controller for dc motor commutator, vice for ac motor controller. Dc motor controller can use commutator to change the direction of the current in the coil, so as to achieve the coil stress in the same direction and the effect of continuous rotation.
