HPEVS AC Electric-Motor Drive Systems (AC-20/AC-23)

The AC 20 motor is 1 1/2" longer derivative of the AC 9/AC 15 motors. This motor produces 65 horsepower out to 5100 RPM and 82 ft./lbs. of torque at 96 volts/650 amps. This motor style is another very popular choice for motorcycles.

The AC 23 motor is same size as its sister motor the AC-20, but has been developed to produce more torque. On the same voltage and amperage as above (96 volt/650 amps), this motor produces 128 ft./lbs. of torque and 56 horsepower out to 3300 RPM.

The weight of this motor is around 60 pounds/27.2 Kg.
