Just a quick question today guys,
I want to buy a cheap bench grinder that has a variable speed controller on it, but they don’t seem to around, and only expensive ones seem to be variable speed controlled.
Now I do know you can’t easily put a speed controller on an induction motor and this is what most bench grinders are made with today.
However a lot of the cheaper ones have brushless motors now.
So my question….
Is it as simple as putting a potentiometer into the circuit, or a dimmer switch?
Or won’t this setup work on a brushless motor?
Thanks again all you wonderful people!
