Electrical gearbox or 3-phase motor has frame with static magnet poles, a first rotor, a second rotor and defined dimensional relationships for a driven first or second rotor

摘要

The device has a frame (3) with static magnet poles, a first rotor (1) with magnetic poles or a rotary field and a second rotor (2) with first rotary current windings (5) for the magnetic poles of the first rotor and second rotary current windings (4) for the static poles, which are connected together in short circuit so that the direction of rotation of the rotary field in the first windings is opposite to that in the second windings. The dimensional relationships of the gear unit or motor are defined for a driven first or second rotor.
