Stator insulation cover, motor stator and motor

Abstract

The invention discloses a stator insulating cover, a motor stator and a motor. The stator insulating cover is used for application on the motor stator. The stator insulating cover includes a plurality of arc-shaped shells, and the plurality of arc-shaped shells each include outer insulating shells connected in sequence. The outer insulating part and the inner insulating part are located on the same side of the side insulating part and are spaced apart from each other; a plurality of shells are sequentially spliced ​​in the circumferential direction to form a circle and defines an annular accommodating cavity for accommodating the ends of the stator windings, the outer insulating parts of the plurality of arc-shaped casings are used to cover the outer end surfaces of the ends of the stator windings, and the side insulating parts are used to cover the outer circumference of the ends of the stator windings The inner insulating portion is used to cover the inner end face of the stator winding end. The stator insulating cover of the invention has good insulation protection effect, simple structure and convenient manufacture, can effectively improve the production efficiency of the motor stator, and at the same time can effectively reduce the end size of the stator winding, reduce the production cost, and is beneficial to the miniaturization of the motor.

Description

technical field [0001] The invention relates to the technical field of stator insulation, in particular to a stator insulation cover, a motor stator and a motor. Background technique [0002] The motor stator is mainly composed of a stator core, a stator winding and an insulating system. In the prior art, the ends of the stator windings are directly exposed or insulated by winding with insulating tape or wrapping with mylar film. At present, some of the end insulating covers are for the stator. The inner ring, outer ring and top of the winding end are insulated as a whole. The traditional insulation scheme has complicated process and poor insulation protection effect. At the same time, in order to consider the creepage distance of the stator winding, the end size is designed to be high, which is not conducive to the miniaturization of the motor. The end of the stator winding is insulated, which has the problems of poor insulation protection effect and high end size. SUMMA...

AI Technical Summary

Problems solved by technology

The traditional insulation scheme has complicated process and poor insulation protection effect. At the same time, in order to consider the creepage distance of the stator winding, the end dimension is designed to be relatively high, which is not conducive to the miniaturization of the motor. There are also some end insulation cover schemes that are not installed near the stator core. The end of the stator winding is insulated, which has the problems of poor insulation protection effect and high end size
