I picked up an Auto scrubber that had 3 Motors. 1 motor is a .5 HP that drove the machine and 2 .75 HP motors that drove the floor scrub pads. These motors are big and weigh about 40+ pounds each. They are 24 volt DC. The .5 says it is 320 rpm and 23 amps. The .75 are geared and 200 rpm and 32 Amps. I don't need to do any speed control but I want to power them from a 120 volt circuit and convert it to 24 volts if possible. I have found a few converters that go as high as 20 amps but none in the 30 amp range. Short of hooking them up to batteries what is the best way for me to power these motors. I want to use them on a mill if possible. Any thing you guys aware of that is out there?
