The Electric Wheel device greatly reduces the complexity and number of parts in a self-contained motor/transmission device while providing redundancy and energy regeneration capabilities. The Electric Wheel is a ring/planetary/sun gear assembly that can be utilized as an infinitely variable transmission, eliminating the need for gear shifting, and greatly reducing the complexity and number of parts needed to construct a transmission. Coupled with two electric motors the device has high efficiency, can overcome dead loads, produce soft-starts and can regenerate energy thru unused torque.
