We were able to purchase a 3HP, 36V DC motor from a seller on eBay. The motor can produce 81.4 N-m of stall torque drawing 1151 Amps. Above is the torque-speed curve for our motor, which was provided by the seller.
The motor weighs about 30 lbs and is quite large. Unfortunately, the motor was designed to have a tapered (Jacob's 33) output shaft, to which we have not entirely figured out how to attach a sprocket. We were also surprised to find 4 wires coming from the motor. We don't understand what the purpose of 4 wires is, but the motor seems to run well when the two red and two black wires are connected to form two combined terminals.
For fun, and also because we accidentally removed an essential bolt from our motor casing, we opened up the motor, revealing the copper windings.

Pls tell me What is working current of motor? U wrote about stalling current. What is AH of batteries you used. And also tell about torque at 1500 RPM of your motor.
