Electrical drive apparatus

摘要

Electrical drive apparatus (10) has an electrical motor (12) arranged to be driven by a power supply means (battery 17). An electrical generator (21) is operatively engaged to said motor (12) for rotation with the rotor (14) thereof. Means for initiating rotation of said motor (12) and said generator means (21) are provided. Electrical energy from said generator means (21) is selectively delivered to said electrical motor (12) to form at least part of said power supply means (17). The drive may be in a vehicle with the motor (12) driving one set of wheels and the generator (21) driven by another. The generator may be connected to a flywheel for energy storage and vehicle may additionally have an engine driving one set of wheels.
