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 comprises a stator part. A rotorpart is arranged in the stator part, the rotor part is provided with a plurality of magnetic poles, and the magnetizing area of at least one magnetic pole in the plurality of magnetic poles and the magnetizing areas of the other magnetic poles are arranged in a non-axisymmetric manner, so that included angle are formed between the geometric center lines of the magnetic poles of the rotor part andthe geometric center line of the stator part in the radial direction. By adopting the motor structure of the structure, the problem that the motor has a starting dead point is effectively solved. Thesingle-phase motor adopting the structure has the characteristics of small size, light weight, simple structure, convenience in large-scale manufacturing and low manufacturing cost.

Description

technical field [0001] The present invention relates to the technical field of motor equipment, in particular to a single-phase permanent magnet self-starting motor and an electric equipment having 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 have begun to consider applying permanent magnet materials to single-phase asynchronous motors to improve the comprehensive performance of household appliances. [0003] The single-phase motor is a single-phase winding, which requires less switching devices to drive the main circuit, and the hardware cost of the control system is low. However, the magnetic field in the single-phase motor is a pulsed magnetic field, and the electromagnetic torque of the motor has a 0-point position. If no specific structure is adopted, the motor stop position (the point where the cogging torque is 0) and th...
