Working of the Circuit. The reverse forward direction of a motor can be achieved using two contactor (K1 & K2) and relay. The K1 contactor is used to switch the three-phase power supply to the motor and run in clockwise direction.. The wiring diagram for a forward reverse motor control typically consists of several components, including a power source, control circuit, motor, and direction control devices. The power source, usually an AC or DC power supply, provides the electrical energy to operate the motor. The control circuit is responsible for controlling the on/off.
Now come to the controlling wiring. Here I had shown that both contactors are 220 VAC. This means that the contactors also required the neutral wire. In the above 3-phase motor forward reverse wiring diagram. The neutral wire first goes to the thermal overload relay NC contacts and the light indicator.. The 3 phase forward and reverse wiring diagram is a schematic representation of the electrical connections required to achieve forward and reverse motion in a three-phase motor. This diagram is commonly used in industrial settings where motors are used to drive heavy machinery or equipment.
