Drive system for electric vehicles

Patent ·
OSTI ID:5688235
A drive system is disclosed for an electric vehicle including an electric motor having a rotatable case and a counter-rotating armature, one being operatively connected to the ground-engaging drive wheels of the vehicle, and one being operatively connected to an electric generator, and rechargeable electric storage batteries connected to the motor to drive it, the generator output being connected in re-charging relation to the batteries. A speed control consists of a drive train whereby the wheel-drive element of the motor may drive the generator-drive element of the motor, thereby stabilizing the speed of the former, whenever the former reaches or exceeds a speed representing a given vehicle speed. A continuously adjustable transmission in this drive train, manually controlled, permits ready adjustment of the vehicle speed.
