A drive system for a high torque mechanical load includes a power supply, a controller, and a high torque electric motor. The electric motor includes a rotor that is oriented eccentrically relative to a stator. In one form, the electric motor has a crankshaft that transmit the torque to the mechanical load. In other variations, the electric motor includes at least two electric motor lobes with opposite stroke positions to provide a smoother output at higher speeds. During operation, the rotor is magnetically attracted to the energized electromagnet. With the rotor attracted to the electromagnet in the stator, the rotor contacts or comes in close proximity to the stator at a contact area. The close proximity between the rotor and stator at the contact area allows very large magnetic forces to be utilized to produce torque without increasing the size or weight of the electric motor.
