Stator insulator and stator

Abstract

The present invention provides a stator insulator combined with a stator of a motor and the stator. More specifically, it relates to a stator insulator for parallel winding of concentrated windings and a stator including the stator insulator. The stator insulator is combined with a stator core The upper part of the stator insulator includes: a plurality of teeth protruding toward the center of the ring-shaped body, the plurality of teeth are combined with each of the plurality of teeth of the stator core , and a plurality of guide joints are protrudingly formed on the outer peripheral surface of the body in a manner corresponding to the plurality of teeth, wound around the three-phase coil of the plurality of teeth and the respective three-phase coils of the three-phase coil The neutral wire coil is arranged on the plurality of guide joints along the outer peripheral surface and in the circumferential direction; each guide joint in the plurality of guide joints is divided and formed with a plurality of guide grooves, and the plurality of guide joints The guiding slots are used to place the three-phase coils and the neutral wire coils respectively.

Description

technical field [0001] The present invention relates to a stator insulator combined with a stator of a motor, and the stator. More specifically, it relates to a stator insulator for parallel winding of concentrated windings and a stator including the stator insulator. Background technique [0002] The technology that serves as the background of the present invention relates to a stator insulator that is bonded to a stator core of a motor and used for wiring a coil wound on the stator core. [0003] In the direct crimping type (Direct Crimping Type) process method that is currently the main applicable parallel connection process, generally speaking, multiple processes based on manual work lead-out lines and neutral line arrangements occur, and a large amount of production is required. Therefore, there is a side effect that the manufacturing cost of the motor is greatly increased compared with the series connection process. In response to this, a bus-type parallel connection ...

AI Technical Summary

Problems solved by technology

[0007] In such reference document 2, a plurality of busbars and structural parts for the motor parallel connection line are also required, so that there is a problem that the material cost of the motor is excessively increased, and due to the occurrence of a plurality of wound coil contact parts However, there is a problem that the connection reliability of the contact part is lowered.

Moreover, there is a problem that a lot of time is consumed in the work of contacting the coil and the bus

[0008] That is, in the conventional technology for parallel winding connection, not only the parallel winding structure itself is not easy to carry out, but also there is a limitation that many parts are consumed for this, which inevitably leads to an increase in manufacturing cost.

Moreover, it is inevitable to spend more time on the production of the motor and the speed of the wire connection, and the instability of the wire connection causes the problem of reduced reliability of the motor.
