Insulator of stator and stator

Abstract

The invention provides a stator insulator combined with a stator of a motor and a stator, and more particularly, relates to a stator insulator for concentrated winding in parallel winding and a statorincluding the stator insulator. The stator insulator is configured to couple to a top portion of a stator core and includes: a main body that has a ring shape; a plurality of insulating teeth that protrude toward a center portion of the main body and that are configured to couple to a plurality of teeth of the stator core, respectively; and a plurality of guide tabs that protrude from an outer circumferential surface of the main body at positions corresponding to the plurality of insulating teeth. The plurality of guide tabs are configured to guide three-phase coils that are wound around theplurality of insulating teeth and neutral coils along the outer circumferential surface in a circumferential direction. Each of the plurality of guide tabs defines a plurality of guide grooves, each of the plurality of guide grooves being configured to seat at least one of the three-phase coils or the neutral coils.

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.
