Reverse DC Motor By 2 Channel Simple RF Remote Control

Generally we use motor controller to reverse motor. Easy wire connection makes it easy to operate. But if you just have ordinary rf remote controls, is it possible to use them to reverse the motor? The answer is yes. The video takes dc motor for example to see how it works.

Firstly you need to prepare:
1 x 2 channel receiver in dc12v (Latched mode)
1 x 3 buttons transmitter
2 x dc12v power adapters
Some lines

K is normally open terminal; B normally closed terminal and D common terminal. Connect terminal K to the positive and connect terminal B to the negative. Terminal D is supposed to be connected to the motor. In order to avoid interference to motor, power supply for the motor and the relays should be different.

Initial state: terminal B & D are normally closed; terminal D & K are normally open. Terminal D outputs negative power and the motor do not work.
Press button ▲ of transmitter, terminal D & K connected to Relay 1 are closed and terminal D & B are open. At this time terminal D outputs positive power, the motor rotates continuously in the positive direction.
Press button ■, terminal D & B connected to Relay 1 are closed and terminal D & K are open. At this time terminal D outputs negative power, the motor stops to rotate.
Press button ▼ of transmitter, terminal D & K connected to Relay 2 are closed and terminal D & B are open. At this time terminal D outputs positive power, motor rotates continuously in the reverse direction.
Press button ■, terminal D & B connected to Relay 2 are closed and terminal D & K are open. At this time terminal D outputs negative power, the motor stops to rotate.
