Electrical three-phase machine for motor vehicle hybrid drive, has inner rotor formed as fan wheel e.g. radial fan wheel, with fan blade, which has radial inner and outer ends, where permanent magnets of rotor are supported by fan blade

摘要

The machine has an inner rotor (2) to generate a magnetic rotary field. An outer rotor (3) with permanent magnets (10) is arranged concentrically to the inner rotor, where a circumferential gap (11) is formed between the inner rotor and the outer rotor. The inner rotor is formed as a fan wheel e.g. radial fan wheel, with a fan blade. The blade has radial inner and outer ends, where the permanent magnets of the inner rotor are supported by the fan blade and are arranged at a radial distance to the inner ends of the blade.
