A motor includes a stator with a first stator, a second stator, and a third stator, each including at least one stator coil, and a rotor including a magnetic element, a first bearing, a second bearing, and a shaft, the stators generating a superimposed magnetic field together causing the magnetic element to rotate. When the magnetic element rotates in the first plane, the outer ring of the first bearing rotates. The center of the first bearing is located in a plane where the second bearing is located, and when the magnetic element rotates in the second plane, the inner ring of the second bearing rotates. A central axis of the shaft passes through the center of the first bearing; wherein the shaft is rotatably fixed to the first bearing and connected to the second bearing.

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.

An electric motor has a stator mechanically coupled to the rotor by a nutating traction interface, such that during nutation of the rotor with respect to the stator a tilt axis of the rotor progresses about the axis of rotation of the output shaft. The rotor and a surface of the stator bound a dynamic gap across which a magnetic field is produced by electrical activation of the motor to generate a force between the rotor and the stator. The traction interface and the gap are arranged such that, in a plane containing the axis of rotation of the output shaft, the traction interface is angled with respect to the stator surface bounding the gap. The rotor is connected to the output shaft by a tiltable connection such as a gimbal.
