Abstract

The invention relates to a combined motor stator component and sleeve used for a wet operation pump. The combined motor stator component and sleeve comprises a stator component and a sleeve, wherein the stator component comprises a stator iron core, a stator coil and a pole piece; a plurality stator teeth distributed at intervals extend integrally from the periphery of the stator iron core, one end of the pole piece is connected with the stator teeth in a matching way, the sleeve is integrally injected on the other end of the pole piece, and one or more positioning parts is/are arranged on the end face or the side face of a non-injection sleeve of the pole piece. The invention further relates to an assembly method of the combined motor stator component and sleeve, wherein the pole piece is placed and located in an injection mold, the sleeve is obtained by injection on the pole piece, then the other end of the pole piece is connected in a matching way with the stator teeth to obtain the combined motor stator component and sleeve for the wet operation pump. According to the invention, the pole piece is stably positioned in the injection mold to guarantee the injection molding effect of the sleeve.

Description

technical field [0001] The invention relates to a motor component for a wet-running pump, in particular to a combined motor stator assembly and casing for a wet-running pump, and the invention also relates to the combined motor stator assembly and bushing for a wet-running pump The assembly method is especially suitable for application in the field of dishwashers. Background technique [0002] The pump is a machine that transports fluid or pressurizes the fluid. Its working principle is to transmit the mechanical energy generated by the pump motor or other external energy to the fluid to increase the energy of the fluid. It is mainly used to transport fluids including water, oil, acid and alkali, Emulsions, suspensions, and liquid metals, etc. Pump motors generally include dry-running pump motors and wet-running pump motors. The dry-running pump motor refers to the overall packaging of the motor, and one end of the rotating shaft protrudes from the overall motor package as...
