SINGLE-PHASE OUTER-ROTOR MOTOR AND ROTOR THEREOF.

摘要

A single-phase outer-rotor motor includes a stator and a rotor surrounding the stator. The rotor includes a housing and a plurality of permanent magnets affixed to an inside of the housing. The permanent magnets are arranged spacedly along a circumferential direction. The stator includes a stator core and windings wound around the stator core. The stator core includes a yoke and a plurality of teeth extending radially outwardly from an outer edge of the yoke. Each of the teeth forms a tooth tip at a distal end thereof. The tooth tip has an outer surface facing the rotor. The permanent magnet is magnetized along the circumferential direction. Two adjacent permanent magnets have opposite magnetization directions. Adjacent surfaces of two adjacent permanent magnets have the same polarity. A magnetic member is disposed between each two adjacent permanent magnets.
