Permanent magnet field-type rotating machine |
摘要 |
Disclosed is a permanent magnet field-type rotating machine of a high efficiency having an internal magnet-type rotor. The rotating machine comprises an internal magnet-type rotor having a plurality of permanent magnets embedded in a rotor yoke, and a stator disposed in opposed, spaced relationship to the rotor, with an air gap formed between the rotor and the stator. The rotor yoke comprises a member in which ferromagnetic regions and non-magnetic regions coexist, and the non-magnetic regions are disposed respectively at those positions of the rotor yoke where leakage magnetic flux is liable to be generated.
