Abstract: A single-phase outer-rotor motor includes a stator and a rotor surrounding the stator. The stator includes a stator core and windings wound around the stator core. The stator core includes a yoke and a plurality of teeth. Each of the teeth forms a tooth tip at a distal end thereof. A slot opening is formed between each two adjacent tooth tips. The rotor includes a housing and a permanent magnet affixed to an inside of the housing. The permanent magnet forms a closed ring in a circumferential direction. The permanent magnet forms a plurality of magnetic poles along the circumferential direction. An outer surface of the stator and an inner surface of the permanent magnet define there between a symmetrical uneven gap. A width of the slot opening in the circumferential direction is less than or equal to five times of a minimum width of the gap.

Abstract: A single-phase brushless motor includes a stator and a rotor rotatable with respect to the stator. The rotor includes a number of permanent magnetic poles. The stator includes a stator core and a winding wound on the stator core. The stator core includes an outer annular portion, an inner annular portion, and connecting portions connecting the inner and outer annular portions. The winding is wound around the connecting portions. The rotor is received in the inner annular portion. The inner annular portion and the rotor form a substantially uniform air gap. A recess is formed in an inner surface of a part of the inner annular portion between each pair of adjacent connecting portions. A center of each recess deviates from a center line of symmetry of the corresponding pair of connecting portions.
