The invention provides a single-phase permanent magnet self-starting motor and electric equipment with the same. The single-phase permanent magnet self-starting motor includes a stator part and a rotor part. The rotor part is arranged in the stator part. Each magnetic pole of the rotor part is provided with a first permanent magnet and a second permanent magnet. The first permanent magnet and the second permanent magnet The remanent magnetization of the magnets is set differently so that the geometric centerline of the magnetic poles of the rotor part is arranged at an included angle with the geometric centerline of the stator part in the radial direction. By arranging the permanent magnets of the rotor iron core part to be composed of two kinds of permanent magnets with different residual magnetization strengths, so that there is an offset angle between the geometric centerline of the magnetic poles on the rotor part and the geometric centerline of the stator part, the structure is adopted The unique motor structure effectively solves the problem of the motor starting dead point. The single-phase motor adopting this structure has the characteristics of small size, light weight, simple structure, convenient large-scale manufacturing, and low manufacturing cost.
Description
technical field [0001] The invention relates to the technical field of motor equipment, in particular to a single-phase permanent magnet self-starting motor and electric equipment with the same. Background technique [0002] With the rapid development of permanent magnet motors, the demand for single-phase motors in the field of household appliances is also increasing. People began to consider applying permanent magnet materials to single-phase asynchronous motors to improve the overall performance of household appliances. [0003] The single-phase motor has a single-phase winding, fewer switching devices are required to drive the main circuit, and the hardware cost of the control system is low. However, the magnetic field inside the single-phase motor is a pulsating magnetic field, and the electromagnetic torque of the motor has a zero point. If no specific structure is adopted, the stop position of the motor (the point where the cogging torque is 0) coincides with the poi...
