Torque Control For DC Permanent Magnet Motor


Thread Starter


I am trying to design a simple torque control for a dc permanent magnet motor. Would anyone please advise me on any circuit that can do that? Thank you very much.

The ratio of output torque of a DC motor to its current is approximately constant and is available in the manual of DC motors (torque constant). Therefore, torque control of DC motors is available through current control of DC motors.

A document about current control of DC motors involving methods and a laboratory project is available at:

In addition, schematic and PCB design of this project are available at:
does anybody know wich program I should use to open those schematics????

thanks for your answer
