In the circuit the motor terminals are connected between the two common poles of the relay. In the above 3 phase motor forward reverse wiring diagram.

From the 2nd thermal overload relay normal close contacts the supply goes to the both contactors coil contactsterminals. And the second switch which is connected in the way of positive wire is used for switch onoff the motor.
The figure given below shows the control and power diagram of forward and reverse starter diagram. Instead of changeover relay contacts the motor is wired between two complementary power transistor outputs which can then be controlled to give full forward and reverse speed control using pulse width modulation and active braking. To run the motor of above 05 hp rating circuit has to made in star delta. The train travels to the down limit switch and reverses. These type of starters are used in various applications eg mixing of materials dying. So here we are using a simple dpdt relay arrangement for polarity alternation.
This sends a pulse to the latching relay to reverse the motor and ends the short pulse. Two one way switches used. Also read dpdt relay wiring diagram. The neutral wire first goes to the thermal overload relay nc contacts and to the light indicator. These forward and reverse starters are dol type and not used above the 05 hp motors. Automatic forward reverse a motor the following circuit allows a motor such as a train to travel in the forward direction until it hits the up limit switch.
In the above forward reverse dc motor using relay double pole double throw relay wiring diagram. Dc motor reversing circuit using dpdt relay the direction of a dc motor can be controlled with the input polarity at the motor terminals. How to make dc motor forward reverse control using relay diy project the backbenchers diy duration. A switch is used to turn dc direct current motor forward and reverse.
