Description

A kind of electrical machine insulation stator

Technical field

The utility model belongs to technical field of motors, is specifically related to a kind of insulation stator of automobile-used motor.

Background technology

At present, the insulation gummed paper is mostly adopted in insulation between the groove of motor stator winding, and manufacturability is poor, and insulating properties is subjected to the influence of artificial qualification, and when output in enormous quantities, efficient and insulation property are subjected to serious restriction; The winding surface insulation only adopts dipping lacquer to handle mostly in addition, and does not have supplemental dielectric layer, compares under the condition of severe in the motor service conditions like this, and the stator water inlet can cause insulation to descend, and causes motor to damage.

Summary of the invention

The purpose of this utility model is at the deficiencies in the prior art part, and a kind of insulation stator of simple in structure, rotary electric machine for vehicles that insulation property are high is provided, and increasing the insulation property of stator, and makes it simple in structure, is beneficial to realize the miniaturization of motor.

For achieving the above object, the utility model adopts following technical scheme:

A kind of electrical machine insulation stator, it comprises stator body, described stator body is made of insulation winding and stator core; At the wiring face of described stator body insulating barrier is installed, non-wiring face at stator body is equipped with insulating barrier down, on the upper and lower insulating barrier installing hole is arranged, and the installing hole of upper and lower insulating barrier is corresponding one by one with the installing hole of stator body, in installing hole, be cast with thermosetting resin, upper and lower insulating barrier and stator body are connected as one; The position that the three-phase alternating current binding post of corresponding stator body is drawn on last insulating barrier is provided with outlet, and three-phase alternating current binding post outlet is thus drawn.Described upper and lower insulating barrier adopts the heat-resistant resin material to make.

Described insulation winding is made of insulation framework and enameled wire loop, and enameled wire loop is wound on the insulation framework, and insulation framework is inserted into the groove of stator core and the boss between the groove by insulation framework.Described insulation framework is injection molded by hard insulation.

This utility model increases insulating barrier by the upper and lower surface at stator body, can increase the insulation property of stator; Further, by in the insulation winding, designing insulation framework, adopt this structure, insulation framework is the finished product that makes in advance, has reliable and stable insulation effect after forming the insulation winding, its insulation property just are not subject to the influence of workman's qualification, when guaranteeing the product insulation property, can enhance productivity greatly.This shows that the insulation stator after this improvement is simple in structure, the production efficiency height, and can realize the miniaturization of motor, and especially can promote the insulation property of motor greatly, motor can be worked under the environment of higher temperature rise.
