Motor stator insulation framework

Abstract

The invention proposes a motor stator insulation frame, which includes two frame bodies. The frame body includes an end ring, an inner ring groove and an outer ring groove. The end ring, the inner ring groove and the outer ring groove are arranged in a staggered manner. The end ring, the inner ring groove and the outer ring groove are integrally formed by injection molding. There are several insulation gaps with different depths on the outside of the end ring, and there are wire retaining protrusions on the outside of the insulation gap rise. This structure only needs one injection mold to complete the injection molding of the insulation frame of the motor stator, which reduces the investment cost of the mold, saves production time, and improves production efficiency; through the cooperation of the insulation gap and the protrusion of the retaining line, the transition line can be Naturally separated to a reliable insulation distance, no need for further insulation treatment, saving preparation time and materials.

Description

Technical field [0001] The invention relates to the technical field of motor and generator frame, in particular to a motor stator insulation frame. Background technique [0002] When the motor is manufactured, the stator of the motor is generally required to be lined with an insulating layer and varnished when it is embedded in the coil of the enameled wire winding to improve the insulation performance of the stator armature. The traditional method is to line a green shell paper with good insulation between the stator core and the winding of the enameled wire coil, and then insert a bamboo slot stick to plug the coil tightly and then dry it with paint. In recent years, a plastic frame is usually used for isolation and insulation of a small micro motor. The stator produced by this process has a neat appearance, good insulation performance, high production efficiency and low cost, and is widely used by many manufacturers. [0003] At present, the insulating materials of the stators...

AI Technical Summary

Problems solved by technology

[0003] At present, the insulating material of motor and generator stator is made of paper insulating material or insulating material of solid structure, and the insulating material of solid structure is generally injection molded by injection mold, which has the advantages of compact structure, reliable insulation distance and stable placement, but this The insulation of the solid-like structure is generally composed of 2-3 sets of injection molds, and the cost of the mold is relatively high; at the same time, there are molds at the end, and the insulation in the groove has a mold in the groove. After assembly, a complete motor insulation is formed. Manufacturing and assembly More man-hours are consumed in the process
