::)I found a strong DC motor which I want to use to drill PCBs. It has a tacho-generator output which I think can be used to automatically control a preset rpm.
On a varying load the motor rpm will decrease or increase. It should also be run on 24V for maxium power to give at least 20.000 rpm.

Does anybody have a circuit ready to achieve control?

Thank You.
