    摘要: A fluid generating device and an electric apparatus utilizing the fluid generating device are provided. The fluid generating device includes a motor (10) and an impeller (100) driven by the motor. The motor (10) is a single phase direct current brushless motor which includes a stator (20) and a rotor (50). The stator (20) includes a stator core (30) and a stator winding (39). The stator core (30) includes an outer ring portion (31), teeth (33) extending inwardly from the outer ring portion (31), a pole shoe (35) formed at the tooth (33). Slot openings (37) are formed between the pole shoes (35). The rotor (50) is received in a receiving chamber defined by the pole shoes (35). Inner surfaces of the pole shoes (35) and the rotor (50) form therebetween a substantially even air gap. The presence of even air gap can reduce the cogging torque of the motor (10), thus reducing the startup current and noise of the motor (10).

    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.

    摘要: A single phase motor (10) and a hair dryer (100) are provided. The motor includes a stator (20) and a rotor (50). The stator (20) includes a stator core (30) and a stator winding (39). The stator core (30) includes an outer ring portion (31), teeth (33) extending inwardly from the outer ring portion (31), and two pole shoes (35) extending from a distal end of each tooth (33). A winding slot is formed between each two adjacent teeth (33). A slot opening (37) is disposed between the pole shoes (35) of the adjacent teeth (33), and is offset from one of the two adjacent teeth (33). The air supplying unit (710) includes the single phase motor (10) and an impeller (711). The startup angle and cogging torque of the motor (10) are adjustable by adjusting the position/width of the slot opening (37), without the need of additional positioning slots or positioning holes defined at the pole shoes (35), which makes the motor structure simple.
