    Abstract: A single phase permanent magnet motor includes a stator. The stator includes a stator core and windings. The stator core includes a ring portion, tooth bodies extending radially from the ring portion, and a pole shoe extending from a distal end to two circumferential sides of each tooth body. Each pole shoe defines a positioning slot. A center of each positioning slot is offset from a center of symmetry of one adjacent tooth body so that a torque fluctuation of an output torque of the single phase permanent magnet motor during operation is less than 50%. As a result, the motor vibration and noise are small.

    Abstract: A single phase permanent magnet motor includes a stator core, windings, and a permanent magnet rotor. The stator core includes an end portion and two spaced arm portions each including a connecting arm and a pole claw. Each pole claw has a long pole tip and a short pole tip, and forms a pole surface. The long pole tip of each pole claw corresponds to the short pole tip of the other pole claw with a slot opening formed there between. The slot opening causes the arc pole surface to be discontinued along a circumferential direction, and the arc pole surface is recessed inwardly to form a startup groove.

    Abstract: A motor and methods for making and using same. The motor includes a rotor including magnetic poles and a stator comprising a stator core and a winding wound on the stator core. The stator core includes a plurality of stator teeth each including a tooth body and a tooth end faulted at an end of the tooth body, the tooth end comprising first and second arcuate regions facing the rotor. When the winding is not energized, a first magnetic coupling between said first arcuate region and a selected magnetic pole of said rotor is greater than a second magnetic coupling between said second arcuate region and the selected magnetic pole, said first arcuate region being offset from a selected tooth body in such a way as to enable movement of said rotor to initiate in either of two opposite directions relative to said selected tooth body upon energizing the winding.

    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.
