DC motor forward and reverse control circuit a
Source: InternetPublisher:张小哥 Keywords: DC motor control circuit forward and reverse control AC contactor Updated: 2020/05/25
When SB2 is pressed in the control circuit, the coil of AC contactor KM1 is energized, the moving main contact KM1 of KM1 is connected, and the DC motor
M rotates forward; when SB3 is pressed, the coil of AC contactor KM2 is energized. The moving main contact KM2 of KM2 is turned on, the circuit is cross-connected,
the current flow direction in the armature circuit is changed, and the DC motor M is reversed. Interlocking is implemented in the circuit. When one branch is connected, the other branch is immediately cut off
. The RP can change the speed of the motor. As shown in Figure 4-25a. For forward and reverse rotation control of series-wound DC motors ,
