HPEVS AC Electric Dual Motor Drive Systems (AC-34x2/AC-35x2)

There are two designs of the AC 3Xx2 motor. Both the AC34X2 and the AC35X2 are designed for automotive applications (up to 3500 lbs) but can be used in a multitude of applications. The design of the motor is as such that there are two rotors on one common shaft. The frame of this motor includes the two stators which combined with the rotor shaft and the remaining parts, the result is a really nice motor package. The motor will have approximately double the torque and horsepower that the single AC-34 and AC-35 motor has now.

The weight of the AC-3Xx2 motor is around 150 pounds/68Kg.
