Embodiment 1

[0036] as attached figure 1 and 2 As shown, a motor stator, which is an annular outer stator, includes a stator core 1 and a winding 2. It is characterized in that the wire slot 3 of the stator core is an open slot, and the wire teeth 4 are equal-width teeth ; The winding 2 is an integrally formed winding; each integrally formed winding is integrally sleeved on the embedded wire teeth of a stator core, and the integrally formed winding is a single-layer structure in the embedded wire groove of the stator core, On the top of the equal-width teeth of the stator core, there is a slot wedge installation slot 6 at the side port of the embedding slot. The slot wedge 7 is inserted in the slot wedge installation slot 6, and the annular integrally formed winding is prevented from falling by the slot wedge 7. The integrally embedded winding is made of self-adhesive enameled wire, which is initially wound into a winding through a mold, and then the winding is shaped and fixed by a mold ...

Abstract

The invention provides a single-layer overall wire embedding method for motor stator windings. Overall embedding molding windings are wrapped with enamelled wires; motor stator open wire embedding slots with equal-width tooth structures are manufactured on an iron core of a motor stator; stator wire embedding teeth formed on the motor stator are equal-width teeth; and the overall embedding molding windings are embedded into the motor stator open wire embedding slots in a single-layer overall embedding manner. The overall embedding molding windings are directly embedded into the open slots as a whole. The equal-width tooth structures and the single-layer overall embedding molding windings are adopted, and fixing and molding are carried out through a mold, so that the windings become the overall embedding molding windings; the wires of the windings can be tightly attached together; and the problems of intersection and interference among the windings can be effectively solved. The end parts of the windings are relatively short, so that the wire embedding technology is greatly simplified; the space filling factor can reach over 90%; the overall embedding molding windings are reasonable in structure; and the mechanical strength is higher than that of dispersedly embedded coils.

Description

technical field [0001] The invention relates to a manufacturing method of motor components, in particular to a method for embedding wires of motor stator windings, which is mainly used for embedding wires of motor stator windings; it belongs to the technical field of motor manufacturing. Background technique: [0002] The motor is formed by a combination of a stator and a rotor, where the motor stator is the stationary part of the motor. The stator is composed of three parts: stator core, stator winding and frame or mandrel. The stator winding of the motor stator can be divided into two types: centralized and distributed according to the shape of the coil winding and the way of embedded wiring. According to the different arrangements of embedded wiring, distributed windings can be divided into two types: concentric and stacked. [0003] (1) Concentric winding: Concentric winding is several rectangular coils of different sizes in the same coil group, which are arranged one ...
