General Mach Discussion / Re: Lathe motor question "Variable Speed"

I will suggest the alternativeĀ - which isĀ - replace your spindle motor with a three phase motor (about twice the power) then use a single phase to 3 phase inverter to control the speed. PWM and M3 and M4 signals are readily available from Mach 3.
I say "twice the power" becasue you do loose torque at lower speeds with an inverter - but I am assuming you have a gearbox on the Harrisson
I only say this becasue I've done it, and I know Hood has done the servo option - the choice is yours.
