Stator insulation cover, motor stator and motor

Abstract

The invention discloses a stator insulation cover, a motor stator and a motor. The stator insulation cover is applied to the motor stator; the stator insulation cover comprises a plurality of arc-shaped shells; each arc-shaped shell comprises an outer insulation part, a side insulation part and an inner insulation part which are connected in sequence, wherein the outer insulation part and the inner insulation part are positioned on the same side of the side insulation part and are opposite to each other at an interval; the shells are sequentially spliced in the circumferential direction to form a circle and define an annular containing cavity used for containing the end of the stator winding; the outer insulation parts of the arc-shaped shells are used for covering the outer end face of the end of the stator winding; the side insulation parts of the arc-shaped shells are used for covering the outer circumferential face of the end of the stator winding; the inner insulation parts of the arc-shaped shells are used for covering the inner end face of the end part of the stator winding. The stator insulation cover is good in insulation protection effect, simple in structure and convenient to manufacture; the production efficiency of the motor stator can be effectively improved; and meanwhile, the end size of the stator winding can be effectively reduced; the production cost is reduced; and miniaturization of the motor is facilitated.

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 stator core, stator winding and insulation system. In the existing technology, the end of the stator winding is directly exposed or insulated by insulating tape winding and polyester film wrapping. The current part of the end insulation cover is for the stator. The inner ring, outer ring and top of the winding end are integrally insulated. 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 windi...

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
