Single relay control forward and reverse and speed control circuit schematic

Posted by: admin  • Information section:Control circuit

Idea: Using a single-pole double-throw relay to control the motor's forward and reverse design is very good, but how to make the motor stop and speed regulation is not easy to think of. Let the motor stop, you can use the triode to open and close the circuit, MOS tube can also. This can be achieved by combining them.
Schematic:
 


After the actual welding circuit board test, the purpose of positive reversal and speed regulation can be achieved.
The relay type used is: TQ2-5V, and TX2-5V is also available. (The actual application can check the relevant datasheet to understand its pin distribution and function)
The welding is as follows:
