Abstract

The invention discloses a motor and a water pump comprising the same. The motor comprises a rotor and a stator, wherein the stator is arranged outside the rotor; the stator comprises a stator yoke portion formed in an annular shape and a plurality of stator teeth arranged in the circumferential direction of the stator yoke portion at intervals; the stator yoke portion is formed by superposing a plurality of yoke portion punching sheets in the axial direction of the stator yoke portion; each stator tooth is formed by superposing a plurality of tooth portion punching sheets in the circumferential direction of the stator yoke portion; the superposing direction of the plurality of yoke portion punching sheets is perpendicular to that of the plurality of tooth portion punching sheets; one end, adjacent to the rotor, of at least one stator tooth is provided with at least one tooth shoe portion, and the tooth shoe portions extend along the axial direction of the rotor; one end, away from the corresponding stator tooth, of the at least one tooth shoe portion is provided with a boss; and the bosses extend toward the direction of the rotor. According to the motor disclosed by the invention, the utilization rate of an axial magnetic field of the rotor is improved, the reluctance is reduced, the magnetic conduction effect between the stator and the rotor is improved, and the magnetic concentration effect is better.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a motor and a water pump with the same. Background technique [0002] In related technologies, the stator and rotor of a motor (such as a small motor) are easy to install, the slot fill rate and the performance of the motor are indicators that motor manufacturers have been expecting to improve. Some manufacturers have adopted the method of separating the stator core, dividing the stator, and then splicing it into a whole motor. However, this only improves the slot fullness rate of the motor, but the utilization of the rotor axial magnetic field of the motor is not complete, which affects the performance of the motor. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, an object of the invention is to propose an electric machine with a high performance. [0004] Another object...
