Abstract

The invention provides a single-phase permanent magnet motor and a dust collector with the same. The single-phase permanent magnet motor comprises a plurality of stator teeth, the plurality of statorteeth form an accommodating cavity for accommodating the rotor part, and a notch of a stator groove is formed between the tooth boot parts of the adjacent stator teeth. The number of the notches is multiple. The plurality of notches are arranged at intervals along the circumferential direction of the rotor part, and the structural characteristic of at least one notch in the plurality of notches isdifferent from the structural characteristics of the other notches. By setting the notches of the stator slots to have different structural characteristics, the problem that dead points exist in motor starting in the prior art is solved, and the starting torque and the output torque of the motor can be improved. Compared with a common single-phase permanent magnet motor, the cogging torque of themotor is greatly reduced, the torque ripple is greatly reduced, and the starting torque and the output torque of the motor are obviously improved.

Description

technical field [0001] The invention relates to the technical field of motor equipment, in particular to a single-phase permanent magnet motor and a vacuum cleaner with the same. Background technique [0002] 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 coincides with the point where the electromagnetic torque is 0. At this time, no matter what current is passed through, the motor cannot start, so there is a problem of starting dead point. [0003] Generally, single-phase permanent magnet motors use unequal air gaps and asymmetrical teeth to solve the problem of starting dead points. For example: the single-phase motor in the patent publi...
