The train travels to the down limit switch and reverses. In the circuit the motor terminals are connected between the two common poles of the relay.

Forward reverse motor control using relay. The backbenchers diy 3947 views. Also read dpdt relay wiring 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. This sends a pulse to the latching relay to reverse the motor and ends the short pulse. The figure given below shows the control and power diagram of forward and reverse starter 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. In the above 3 phase motor forward reverse wiring diagram. 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. The neutral wire first goes to the thermal overload relay nc contacts and to the light indicator. In the above forward reverse dc motor using relay double pole double throw relay wiring diagram. So here we are using a simple dpdt relay arrangement for polarity alternation.
These type of starters are used in various applications eg mixing of materials dying. These forward and reverse starters are dol type and not used above the 05 hp motors. And the second switch which is connected in the way of positive wire is used for switch onoff the motor. Two one way switches used. A switch is used to turn dc direct current motor forward and reverse. Turn a ceiling fan into a wind turbine generator.
From the 2nd thermal overload relay normal close contacts the supply goes to the both contactors coil contactsterminals. To run the motor of above 05 hp rating circuit has to made in star delta.
