Abstract

The invention discloses a motor and a water pump provided with the same. The motor comprises a rotor, a stator and a plurality of coils, and is characterized in that the stator is arranged outside the rotor, the stator comprises an annular stator yoke portion which is formed by bending a plurality of bar-shaped yoke portion punching sheets superimposed along the axial direction and a plurality of stator teeth which are arranged at intervals along the circumferential direction of the stator yoke portion, the stator teeth are formed by superimposing a plurality of tooth portion punching sheets along the circumferential direction of the stator yoke portion, the superimposing direction of the plurality of yoke portion punching sheets is perpendicular to the superimposing direction of the plurality of tooth portion punching sheets, one end of each bar-shaped punching sheet is provided with a protruding portion, and the other end of each bar-shaped punching sheet is provided with a sinking portion matched with the corresponding protruding portion; and the plurality of coils are wound on the stator yoke portion, each two adjacent stator teeth are provided with a coil therebetween, and an insulating piece is arranged between each coil and the stator yoke portion. According to the motor disclosed by the invention, the production efficiency of the stator yoke portion is improved, materials of the stator yoke portion are saved, and the material cost is reduced. In addition, the slot fullness rate of the stator is further effectively improved, and the performance of the motor is improved.

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 adopt the assembly method of separating the stator teeth from the stator yoke, modularize the stator teeth, winding, stator yoke and other components to simplify the division process, and then weld each component into a motor as a whole. However, the assembly and production process of the motor is complex. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, an object of the present invention is to provide an electric motor, the assembly process of which is simple and the sl...
