Single Phase Permanent Magnet Motor And Stator Core Thereof

摘要

The present invention provides a stator core comprising an end portion and a pole arm extending from the end portion. The pole arm includes two spaced connecting arms and two pole claws respectively formed at distal ends of the connecting arms. The two pole claws define a space for receiving a rotor therein. The pole claws surround the space and form an arc pole surface. The arc pole surface forms a discontinuity opening along a circumferential direction. The discontinuity opening faces a spacing between the connecting arms and has a width changed along an axial direction.
