The invention relates to a 10 w double-rotating-speed single-phase asynchronous motor, and belongs to the technical field of motors. The single-phase asynchronous motor comprises a containing cavity formed by a front end cover and a rear end cover, a stator core is arranged in the containing cavity, a rotor core is arranged in the stator core, a squirrel cage winding and an end ring are arranged in the rotor core, and the rotor core is fixedly connected with a rotating shaft; a stator winding and a heat protector are arranged in the stator core, the stator winding comprises a main winding, an auxiliary winding and a tapped winding, the heat protector is connected with the main winding through a circuit, the main winding is connected with the tapped winding through a circuit, the tapped winding is connected with the auxiliary winding through a circuit, a power connection end is led out of the position between the main winding and the tapped winding, a power connection end is led out of the position between the tapped winding and the auxiliary winding, and a capacitor C is connected between the heat protector and the auxiliary winding. As the heat protector is additionally arranged in the motor, the single-phase asynchronous motor has the following advantages that the application range of the motor is enlarged, multiple using requirements for the motor are met, when it is monitored that operation temperature exceeds a standard, power is cut off automatically, the service life of the motor is prolonged, and the use safety of the motor is improved.
Description
technical field [0001] The invention belongs to the technical field of motors, in particular to a 10W double-speed single-phase asynchronous motor. Background technique [0002] At present, double-speed single-phase asynchronous motors are widely used in various fields. However, the double-speed single-phase asynchronous motor is limited by its structure, and it is easy to cause the operating temperature to exceed the standard under long-term operation, resulting in the scrapping of the motor and increasing the use cost. Contents of the invention [0003] Aiming at the problems existing in the prior art, the purpose of the present invention is to design and provide a technical solution for a 10w double-speed single-phase asynchronous motor. [0004] The 10w dual-speed single-phase asynchronous motor includes a housing cavity composed of a front end cover and a rear end cover, and is characterized in that a stator core is set in the housing cavity, and a stator core is se...
