Stator of rotating electric machine with field poles with permanent magnet

摘要

This stator of a rotating electric machine with field poles with a permanent magnet, which magnet 2 formed by a cylindrical sector is inserted into a semi-open envelope 3 which is permeable to the magnetic field and is arranged inside a tubular yoke 4, is notable in that the envelopes 3 surrounding the magnets 2 of the field poles following one another in the yoke 4 are formed as a mild steel sleeve 5 fitted inside the said yoke 4. <IMAGE>
