Stator assembly and motor

Abstract

The utility model relates to the technical field of motors, aims to solve the problem of how to improve the slot fullness rate of stator winding, and provides a stator assembly and a motor. The stator assembly comprises a stator framework and a winding. The stator framework comprises an iron core and an insulating layer, the iron core comprises a ring part and a plurality of stator teeth, and the stator teeth are arranged on the periphery of the ring part and distributed at intervals in the circumferential direction of the ring part; the insulating layer is formed outside the iron core through injection molding, and the thickness of the insulating layer is less than 0.3 mm; the outer diameter of the stator framework is 26 mm to 30 mm. The winding is wound on the stator framework. The stator framework has the advantages that the insulating layer is formed outside the iron core through injection molding, the thickness of the insulating layer is reduced, the groove fullness rate of the stator framework and the utilization rate of corresponding enameled wires are improved by setting the thickness of the insulating layer to be smaller than 0.3 mm, and then the motor efficiency is improved; and after the plastic coating process is used for replacing the powdering process, the production reject ratio is reduced, and the production efficiency and quality of the motor are also improved.
