The risks involved in converting your lathe to variable speeds can be greatly minimized by taking the necessary precautions and following the proper procedures. Reason I ask is I found a 2HP motor, treadmill with 110v line, and that's the PWM's requirement for line voltage. 1) Find a used 3Ph motor and run it on a VFD. Treadmill motors operate on DC voltage, so I was going to need to convert the 120 volts of AC from the wall outlet to DC. v belts dont require lots of tension to function properly. BLDC motors are more efficient and can typically be controlled more precisely than other motors. The tachometer kit comes with the tach, sensor and magnets.
