Stator short-pitch double-layer winding phase separation paper installation method

Abstract

The invention discloses a stator short-pitch double-layer winding phase separation paper installation method. The method is characterized by comprising the steps that integrated phase separation paper with layer phase separation paper and end phase separation paper is manufactured; the integrated phase separation paper is arranged in the wire slot of the stator, so that the interlayer phase separation paper is located in the wire slot, and the end phase separation paper at the two ends is located outside the wire slot; the coils are embedded into the corresponding wire slots of the stator one by one, and the parts, located in the wire slots, of the coils are wrapped with the interlayer photographic paper located in the wire slots; in the process of embedding the coils one by one, the end part phase separation paper positioned on the outer side of the wire slot is directly arranged between the end parts of the adjacent coils, and the end parts of the adjacent coils are separated; and the end part phase separation paper is bounded on the end part position of the coil. According to the invention, the installation efficiency can be improved, and the problem of interphase short circuit can be avoided.

Description

technical field [0001] The invention relates to the field of motors, in particular to a method for installing phase-separated paper for short-pitch double-layer windings of a stator. Background technique [0002] Short-pitch winding, also known as short-pitch winding, refers to a winding whose pitch is smaller than the pole pitch. Since the short-pitch winding has many advantages such as shorter ends of the electromagnetic wire, material saving and higher power factor, short-pitch windings are often used in applications. At present, for the short-pitch double-layer winding of the motor stator, the phase separation paper in the inclined slot or straight slot stator coil and the phase separation paper at the end of the coil are split structures. [0003] Such as Figure 4 Shown are layer spacer and end spacer papers, respectively. Layer spacer paper is wrapped around the middle of the coils to insulate the middle of the coils, and end phase spacer paper is placed between the...

AI Technical Summary

Problems solved by technology

The defects of the phase-separation paper of the split structure are: 1. The installation efficiency is low, and the layer separation paper and the end phase separation paper need to be installed step by step; 2. When the automatic wire binding machine binds the end of the stator, the end phase separation The paper will be displaced or even dropped, causing a short circuit between phases and further reducing efficiency
