    I am terrible with electrical and this could solve a problem for me, but I hope someone can help me sort this out.

    I have a 2x72" belt grinder, and it runs on a 1HP motor, with no VFD.

    Would this project be more like running the grinder on a dimmer switch, which I have been warned not to do, or like running it with a variable frequency drive?

    Many thanks,

    G.

    It looks to me like you would just be reducing the voltage to the tool. If you do that with the tool under load that would be a good way to burn out the motor.
