Hey guys.....
I am in the process of building an automated Mirror grinder for telescope primary mirrors....I have a DC motor I need a control for.
I found a couple of PWM circuits online but my problem is I have a 120 vdc 2.25 php motor and the circuit I found is not sufficiant. I found a kit thats rated to 100 volts ..........and may use it as a starting point unless someone here knows a better schematic - I need the PWM to maintain torque at lower RPM's
Any suggestions - I am not the electronics guru - (thats why I allways come here for help !)
here is a link to it :
