Abstract

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; a rotor part, the rotor part is arranged in the stator part, and the rotor part has a plurality of magnetic poles, and the magnetization area of ​​at least one magnetic pole in the plurality of magnetic poles is non-axisymmetric to the magnetization areas of the remaining magnetic poles It is set so that the geometric centerline of the magnetic poles of the rotor part has an included angle with the geometric centerline of the stator part in the radial direction. The motor structure adopting this structure effectively solves the problem that the motor has a 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...
