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 and a rotor part arranged in the stator part, wherein each magnetic pole of the rotor part is provided with a first permanent magnet and a second permanent magnet, the first permanent magnet is arranged on the outer peripheral surface of the second permanent magnet, and the extension line of the geometric center line of the first permanent magnet along the radial direction of the rotor part and the extension line of the geometric center line of the second permanent magnet along the radial direction of the rotor part are arranged at an included angle, so that the geometric center line of the magnetic pole of the rotor part and the geometric center line of the radial direction of the stator part are arranged at an included angle. By adopting the motor structure of the structure, the problem that themotor has a starting dead point is effectively solved. The single-phase motor adopting the structure has the characteristics of small size, light weight, simple structure, convenience in large-scalemanufacturing and low manufacturing cost.
Description
Technical field [0001] The present invention relates to the technical field of electrical 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 overall performance of household appliances. [0003] The single-phase motor is a single-phase winding, which requires fewer switching devices to drive the main circuit, and the control system hardware cost is low. However, the magnetic field in a single-phase motor is a pulsating magnetic field, and the electromagnetic torque of the motor has a zero position. If no specific structure is adopted, the stopping position of the motor (the point where the cogging torque is 0) coincides w...
