Abstract: A single phase motor and a hair dryer are provided. The motor includes a stator and a rotor. The stator includes a stator core and a stator winding. The stator core includes an outer ring portion, teeth extending inwardly from the outer ring portion, and two pole shoes extending from a distal end of each tooth. A winding slot is formed between each two adjacent teeth. A slot opening is disposed between the pole shoes of the adjacent teeth, and is offset from one of the two adjacent teeth. The air supplying unit includes the single phase motor and an impeller. The startup angle and cogging torque of the motor are adjustable by adjusting the position/width of the slot opening, without the need of additional positioning slots or positioning holes defined at the pole shoes, which makes the motor structure simple.

Abstract: An air flow regulating device includes a housing, an air supply unit and a circuit board which are arranged inside the housing. The air supply unit includes an impeller and a single-phase permanent magnet brushless motor configured to drive the impeller. The single-phase permanent magnet brushless motor includes a stator and a rotor which can rotate relative to the stator. The stator includes a stator core and a single-phase winding wound around the stator core. The rotor includes a shaft and a permanent magnet fixed to the shaft. Numbers of magnetic poles of the stator and the rotor are the same and not greater than six. An outer diameter of the stator core is less than 35 mm and/or an axial thickness of the stator core is between 10 mm and 20 mm.

Abstract: A single phase permanent magnet motor includes a stator and a rotor. The stator includes a stator corer and windings. The stator corer includes a yoke portion and stator teeth. Each stator tooth includes a winding portion and a pole shoe connected to an end of the winding portion. Each pole shoe includes a pole face. The pole face defines a first positioning notch at a middle thereof. Each of the pole faces further defines at least one second positioning notch. Said at least one second positioning notches in one of pole shoe are located at the same side of the first positioning notch of the corresponding one pole shoe. The first and second positioning notches are configured such that an initial position of the rotor received in the space of the stator is offset from a dead point position.
