Insulating framework carrying stator winding and motor stator

Abstract

The invention provides an insulating framework carrying a stator winding. The insulating framework carrying the stator winding includes an outer wall and an inner wall which are arranged in an annularly surrounding manner, and a plurality of winding parts which are arranged between the outer wall and the inner wall in a connected manner and used for the winding of the stator winding, wherein the height of the inner wall is small than the height of the outer wall, and a buckle is arranged on the edge of the outer wall and used for fixing a lead-out wire of the stator winding. The invention further provides a motor stator. The motor stator includes the stator winding, a stator core, a stator frame and the insulating framework, and the stator winding is arranged in the insulating framework. The insulating framework provided by the invention has the advantages that the heights of the inner wall and the outer wall are not equal, which can achieve both a higher slot fullness in a slot and a more orderly winding displacement during the winding of the motor stator; the buckle is arranged in the position of the stator lead-out wire to fix the stator lead-out wire, so as to reduce the risk of the scratching of the stator lead-out wire during the rotor running.

Description

technical field [0001] The invention relates to the field of motors, in particular to an insulating skeleton applied to the end of a compressor motor stator for carrying stator windings and a motor stator using the insulating skeleton. Background technique [0002] The motor is composed of two main parts, the stator and the rotor. The motor stator is generally insulated by an insulating skeleton. The insulating skeleton is an injection molded part that is arranged at the end of the motor stator and has a wire-passing structure design. The height of the inner and outer walls of the existing insulating frame is equal, the winding nozzle has a long stroke during the winding process, the wire arrangement in the stator slot of the motor is chaotic, and the winding nozzle is prone to scratch the enameled wire in the stator slot. lead to safety hazards. In the existing insulating frame, the lead-out wires cannot be fixed, and the rotor will scratch the stator lead-out wires durin...

AI Technical Summary

Problems solved by technology

[0003] Based on this, it is necessary to provide an insulating frame for the problems that the inner and outer walls of the insulating frame of the existing motor are of equal height, which easily leads to messy wiring in the stator slot of the motor, and is easy to scratch the enameled wire in the stator slot.
