Control of dc motor controller and reversing

by:Hoprio     2020-07-28
Forward and backward rotation dc motor controller, motor controller clockwise and counterclockwise. The motor is clockwise rotation of the motor is turned, and motor rotate counterclockwise is the reversal of the motor. And reversing control circuit and its principle analysis in order to achieve the motor controller and reversing, as long as any two phase switch connected to the motor controller of three-phase power supply circuit, can achieve the goal of inverter. There are two ways to do this: one is the armature reverse method, namely don't change the field winding terminal voltage, through changing the input voltage of the armature winding to reverse the motor controller. 2 it is reverse excitation winding connection, that is, the armature winding end voltage unchanged, by changing the excitation winding end voltage to adjust the direction of the motor controller, when the two motor controller voltage change at the same time, the direction of rotation of motor controller stays the same.
