Method for puncturing iron core by motor wire-insertion preventing winding

Abstract

The invention relates to a method for puncturing an iron core by a motor wire-insertion preventing winding, which is technically characterized in that: tips around the opening of wire-insertion grooves at two end faces of the iron core are firstly shaped into rounded corners R and an insulating end plate is then bonded when stators and rotors and magnetic pole iron core of the motor are manufactured; and the winding is led out of the opening of the end plate of the iron core with a particular linear section away from the end plate when the wire insertion for stator assembly and magnetic pole assembly is implemented so as to lower the possibility of causing the opening of the insulating end plate to deformation; the method according to the invention can effectively avoid the insulating damage of the winding after the wire insertion of the motor winding and guarantee the processing quality and the reliability of stator, rotor assemblies of the motor. Such technique is simple and economical in operation, easy for popularization and application, capable of bringing a great many economic and social benefits and suitable for the manufacturing of insertion winding assemblies, such as rotor assembly and stator assembly of the motor with the insulating end plate, etc.

AI Technical Summary

Problems solved by technology

At present, the structure of the motor stator and rotor core with insulating end plates is that the stator and rotor core punching sheets are laminated into a stator or rotor core according to the requirements of the number of core laminations and the thickness of the stack, and then fastened. The insulating end plates are respectively glued to the two end faces of the stator or rotor iron core, and when inserting or winding the wires, the wrong piece in each inserting slot of the iron core is repaired and cleaned, and this traditional process is used for production and processing. The motor stator or rotor iron core has the most problems in the actual production of embedded wires. The insulation of the winding at the slot of the iron core is easy to damage, resulting in breakdown failure of the winding withstand voltage test, especially the small size of the winding end requires high withstand voltage value. After the embedded winding of the stator and rotor components of the aero-generator, the insulation breakdown of the winding to the core is more common
