I am currently using a raspberry pi to control the speed of a 12v dc motor and it works perfectly fine right now like this. 1pcs 5a double pole double throw dpdt self locking bistable relay module for led motor smart home control dc6 24 loading.

Dpdt relay motor control. Autoplay when autoplay is enabled a suggested video will. Change motor direction with dpdt relay as you can see in the schematic the 12v battery or use other voltages is connected with the plus at terminal t1 and minus at terminal t2. In the circuit the motor terminals are connected between the two common poles of the relay. The contact 1 and 4 are connected together as 2 and 3 are too. The no terminals of the relay get power only when the relay is powered. When the relay receives 12 volts of power the relay snaps from the nc position to the no position.
So here we are using a simple dpdt relay arrangement for polarity alternation. The red led and the dc fan now shut off and the green led and the dc motor now turn on and operate. I can start stop and ramp up the dc motor speed. Spdt relay dpdt relay relay is a electro mechanical switch used to control high power application through low power signal electronic circuits for an example a simple timer circuit working under 5v dc bias can not control high voltage light bulb by introducing relay component we can easily control light bulb. Dc motor reversing circuit using dpdt relay the direction of a dc motor can be controlled with the input polarity at the motor terminals.
