Hello neiji1000


If you use a switching voltage controller rather than a linear voltage controller, you can monitor the voltage generated by the motor during the OFF period. This voltage is proportional to the speed of the motor and can be used to regulate the speed.

This is commonly done in industrial DC motor controllers, and while not as accurate as a tacho feeback system, it is perfectly adequate for most installations.


Best regards,
