摘要: A brushless motor includes a stator and a rotor. The stator includes a stator core and two windings. The stator core includes a yoke, two opposing first teeth, and two second teeth. The windings are respectively wound around the two first teeth. The second teeth are not wound with any winding. The first and second teeth are alternatively arranged. The rotor is received in a space cooperatively bounded by the pole shoes of the main and second teeth. Air gaps are formed between an outer circumferential surface of the rotor and respective pole faces of the first teeth and the second teeth. Each of the air gaps is uneven in radial thickness.

摘要: A brushless motor includes a stator and a rotor. The stator includes a stator core and two windings. The stator core includes a yoke, two opposing first teeth, and two second teeth. The windings are respectively wound around the two first teeth. The second teeth are not wound with any winding. The first and second teeth are alternatively arranged. The rotor is received in a space cooperatively bounded by the pole shoes of the main and second teeth. Each of the main pole shoes is connected to the adjacent one of the auxiliary pole shoes through a magnetic bridge having a larger magnetic reluctance than that of the main pole shoes and the auxiliary pole shoes, which reduces the magnetic leakage and increases the motor power density.

摘要: 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 tooth 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 plurality of permanent magnets affixed to the housing. The permanent magnet is an asymmetrical structure. A radial distance between an inner surface of the permanent magnet and an outer surface of the tooth tip varies along the circumferential direction. The stator and the rotor define an asymmetrical uneven gap there between, and 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.
