I'm not famillar with these design to drive small motor like size of a sewing motor either AC or DC. Roughly 1/10 hp. Also reversing (switch), variable speed via foot pedal. I have access to high current IGT (spelling?) transistors off the old junk plasma TVs. These comes in paralleled transistors instead of one module so easy to adapt.
This is to drive a watchmaker's lathe as this came without one.
Yes, I have many hobbies, seriously.
