Rotor for permanent magnetically excited electrical machines e.g. electromotor, has rotor main structure comprising several magnetic poles that are provided corresponding to number of projections provided in ferromagnetic baffle

摘要

The rotor (4) has a rotor main structure (9) comprising a multi-pole anisotropic rotor magnet (10) which is made of plastic-bonded permanent magnet material. The rotor main structure has several magnetic poles that are provided corresponding to number of projections (12) provided in a ferromagnetic baffle (11). The projections are extended over whole length of the rotor main structure along axial direction.
