摘要: An air flow regulating device (100) includes a housing (110), an air supply unit (130) and a circuit board (140) which are arranged inside the housing (110). The air supply unit (130) includes an impeller (131) and a single-phase permanent magnet brushless motor (10) configured to drive the impeller (131). The single-phase permanent magnet brushless motor (10) includes a stator (101) and a rotor (60, 102) which can rotate relative to the stator (101). The stator (101) includes a stator core (212) and a single-phase winding (1011) wound around the stator core (212). The rotor (60, 102) includes a shaft (551) and a permanent magnet (66) fixed to the shaft (551). Numbers of magnetic poles of the stator (101) and the rotor (60, 102) are the same and not greater than six. An outer diameter of the stator core (212) is less than 35mm and/or an axial thickness of the stator core (212) is between 10mm and 20mm.
