Abstract
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.
