3 phase motor control circuit diagram forward reverse pdf. The control circuit may not be at the same voltage as the power circuit. Now in the below diagrams three phase motor will rotate in two directions viz forward and reverse. In the diagram i connect the incoming three phase supply l1 l2 l3 to the mccb circuit breaker molded case circuit breaker. Explain how the reversal of motor direction is accomplished with two different motor starters m1 and m2. Forward reverse 3 phase ac motor control circuit diagram electrical engineering updates. Typical starter wiring diagram three phase.
Three phase motor connection stardelta y δ reverse and forward with timer power control diagram as we have already shared the starting method of three phase motor by star delta starter with timer circuit power and control circuits. The control circuit is separate from the motor circuit. If the volt ages are different it is called separate control. The circuit shown here provides two direction control forward and reverse for a three phase electric motor. A wiring diagram is a simplified conventional pictorial representation of an electrical circuit. Motor protection 8 3 notes on engineering 8 15 circuit documents 8 19 power supply 8 21 control circuit supply 8 24 contactor markings 8 25 direct on line start of three phase motors 8 26 control circuit devices for direct on line start 8 34 star delta switching of three phase motors 8 35 control circuit devices for star delta starting 8 45.
Direct start 2 directions of rotation. A motor controller might include a manual or automatic means for starting and stopping the motor selecting forward or reverse rotation selecting and regulating the speed regulating or limiting. In the event of an overload both motor starter output. It reveals the components of the circuit as simplified forms as well as the power as well as signal links in between the tools. Variety of single phase motor wiring diagram forward reverse. The overload contacts are connected to l1 on one side and to the plcs input module on the other input 003.
Figure 5 forwardreverse motor wiring diagram. Forward reverse motor control diagram for three phase motor for three phase motor forward reverse control circuit. Three phase motor connection stardelta y δ reverse forward with timer power control diagram starting stopping of 3 phase motor from more than one place power control diagrams control 3 phase motor from more than two buttons power control diagrams. Delta connection electrical circuit diagram ohms law electrical installation electrical engineering electronics projects computer science alcohol dispenser electrical wiring diagram. Here i showed the forward reverse wiring diagram. When the voltage of the control and power circuits is the same it is referred to as common control.
