High-temperature-resistance motor stator

Abstract

The invention relates to the motor technology, in particular to a high-temperature-resistance motor stator which is provided with a stator assembly composed of a plurality of stator iron core sheets, wherein a thermal shrinkage film layer is coated on an outer ring of the stator assembly, the stator assembly is provided with a cylindrical yoke, protruding portions are evenly distributed along the periphery of the inner surface of the cylindrical yoke, line blocking portions expanding towards two sides of the protruding portions are respectively arranged at the ends of the protruding portions, and a winding storage cavity is respectively formed between every two adjacent protruding portions. The cylindrical yoke, the protruding portions and the line blocking portions are of an integrated structure. Transition planes of two lateral walls in the winding storage cavity are curved surfaces. The thermal shrinkage film layer is coated on the outer ring of the stator assembly so that the stator assembly can be effectively prevented from deforming at high temperature; and windings arranged in the stator assembly are stored to be manufactured to smooth transition surfaces, so that stress concentration is reduced, and service life of a motor is prolonged.

Description

technical field [0001] The invention relates to motor technology, in particular to a high temperature resistant motor stator. Background technique [0002] As an essential part of the motor, the stator plays an important role in the motor. Metal wires are wound in the winding storage cavity on the stator. The traditional storage cavity often works for a long time. If it is too high, it will deform, burn out, etc., and some corners in the stator will cause the stator to break instantly after a long time, causing some safety hazards. The outside of the traditional stator is a smooth curved surface, which is a waste of materials on the one hand. On the other hand, the stator becomes bulky, which brings some inconvenience to people's use. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a high-temperature-resistant motor stator so that the motor stator can avoid defects such as burnout and stress concentration after ...
