Description

The drawing-die coil inserting apparatus of motor stator core

Technical field

The utility model relates to motor stator core field, is specifically related to a kind of drawing-die coil inserting apparatus of motor stator core.

Background technology

Winding on motor stator is the chief component of stator core.Stator winding is coupled together in a certain way by coil groups and forms stator circuit, produces induced potential with rotor flux relative motion, realizes mechanical energy-electric energy conversion.Different from setting-in wire laying mode according to the shape of coil winding, centralized and distributed two classes can be divided into.Coiling and the setting-in of centralized winding are fairly simple, but efficiency is lower, and runnability is also poor.The current AC electrical machine stator overwhelming majority is all application distribution winding, according to different machine, model and coil embedding around process conditions, motor designs separately and adopts different winding types and specification, therefore the technical parameter of its winding is not identical yet.

Which kind of mode no matter winding in stator core adopt distribute, and all needs winding to be assembled in stator core, and winding is mainly assembled by the mode of coiling and stator core.For current work flow, majority is that copper cash is wound on basic mode, and then rule to manually, also have adopt artificial not by groove around embedding, process velocity is comparatively slow, and output is lower.To manually the matrix being wound with copper cash winding loaded more time-consuming in stator core body and not easily construct; Artificial coiling is comparatively loose, and during design of electrical motor, copper factor too lowly should not affect stator core performance.
