I'm new here, but have been on this site before for information on EV conversions and such, due to an electric conversion for my 1979 Puch Maxi Sport. The goal is a 12kW hub motor, 6kWh battery pack, custom carbon frame and swingarm, full motorcycle suspension, and full electronics/features to be road-legal. But that's a slow project, and the question for today is for a mini-bike conversion to electric power. It's a Monster Moto MM-B80, and I would like to rip out the stock engine to implement an electric mid-drive system. I've been looking at motors online, and they are far too expensive for this kind of project (just looking to experiment and get some practice before finalizing my plans for the moped).
My knowledge of electric motors is limited, but still more extensive than the average guy in life, and I was wondering if I could take a used motor from Ebay, and rewind it for a totally different voltage and amperage. I would like to take the cheapest foot-mount motor I can find of sufficient size, strip out all the windings and such, and wire it for 48-72VDC, and something like 35-50A. If this is possible, would it matter if the motor was originally AC or DC, brushed or brushless (installing hall sensors isn't a problem afaik), 1/40hp or 4,000hp, single-phase or three-phase? I'd like something like 2000-3000W of power from it, and any RPM that doesn't require absurd gearing. I have my eye on a 115VDC 6.6A motor and I'd like more current and lower voltage. An even better one, if possible, would be a 130VDC 1A motor, but it's a bit small and completely enclosed so I would understand if cooling would be too much of an issue for higher amps.
