摘要： A single-phase claw-pole type motor comprises a stator, which comprises a claw-pole type stator core and toroidally-wound single-phase stator windings, and a rotor that has alternate polarities, wherein a concave part or a convex part is provided on an air-gap surface of claws of the stator core. In addition, the stator core may be configured by compacting magnetic powder, and the single-phase claw-pole type motor may be driven by a converter that converts a direct current to an alternate current according to a position of the rotor.

摘要： A permanent magnet rotating electric machine comprises a stator having stator windings wound round a stator iron core and a permanent magnet rotor having a plurality of inserted permanent magnets in which the polarity is alternately arranged in the peripheral direction in the rotor iron core. The rotor iron core of the permanent magnets is composed of magnetic pole pieces, auxiliary magnetic poles, and a stator yoke, and furthermore has concavities formed on the air gap face of the magnetic pole pieces of the rotor iron core of the permanent magnets, gently tilting from the central part of the magnetic poles to the end thereof. In a permanent magnet rotating electric machine, effects of iron loss are reduced, and an electric car using highly efficient permanent magnet rotating electric machine are realized.
