    摘要: A cooling fan and an air-cooled refrigerator are provided. The cooling fan includes a synchronous motor (10) and an impeller (80). The synchronous motor (10) includes a stator (30) and a permanent magnetic rotor (80). The permanent magnetic rotor (80) includes a rotary shaft (81) and a permanent magnetic rotor main body attached around the rotary shaft. The stator (30) includes a stator core (31) and a stator winding (51) wound around the stator core and powered by an alternating-current power supply. The permanent magnetic rotor operates at a constant rotational speed of 60f/p during a steady state operation of the motor, where f is a frequency of the AC power source and p is the number of pole pairs of the permanent magnet poles. The impeller (100) is connected to the rotary shaft for rotation under the driving of the rotary shaft.

    摘要: A medical pump includes a single phase synchronous motor (80), a rod piston (93), a cylinder (95) for receiving the rod piston (93) for reciprocating motion therein. The single phase synchronous motor (80) includes a stator (20) and a rotor (10) rotatable relative to the stator (20). The rotor (10) includes a plurality of permanent magnets (15). The stator (20) comprises a stator core (21) and a winding (23) wound around the stator core (21). The stator core (21) comprises two opposed pole portions (25) that define there between a rotor receiving space (26) for receiving the permanent magnets (15). The medical pump has a compact structure. In addition, the motor of the medical pump has a constant rotation speed and has a smaller size and less weight under the same output power conditions as traditional motors used in medical pumps. The medical pump is particularly suitable for use in atomizers.
