If its a DC motor, Try a 12v car battery and jumper cables to test the motor.
I had to move my EV project and nothing was working, so to get it from one driveway to another, I just used a 12v battery in the pax seat and jumper cables to the motor. Lots of sparks and amps, but I was able to drive it at a snails pace to the next driveway.
