A method for inserting insulating paper into a motor stator embedding groove

Abstract

The invention provides an insertion method for motor stator line inserting slot insulation paper. In the method, a one-step forming process of insulation paper is divided into multistage forming, forming internal stress of the insulation paper is released in each forming process, and in repeated heating and forming processes, plasticity of the insulation paper is improved, and stability after forming is ensured. The method solves problems that thermal formed insulation paper easily deforms in a cooling process, fit accuracy of the insulation paper and a stator slot is poor, the insulation paper may be reworked, and working efficiency is influenced. A servo motor is used for fixed length transmission, length of insulation paper feeding can be accurately controlled, and when height of a motor line inserting slot changes, just paper feeding length needs adjusting. The servo motor reduces length error of insulation paper feeding, reduces errors of insulation paper length and motor line inserting slot after the insulation paper is inserted, so as to improve integrated performance of a motor.

Description

technical field

[0001] The invention relates to a method for inserting paper, in particular to a method for inserting insulating paper in motor stator slots. Background technique

[0002] The motor refers to an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. The motor is composed of a rotor and a stator. On the stator core of the motor, there are often multiple embedding slots and embedded excitation windings to ensure that the motor can Normal operation; since the field winding is composed of wires, in order to avoid conduction between the field winding and the stator core, even if the insulation between the stator core and the field winding is maintained, there are currently two methods: the first method, Injection molding is used to form an insulating layer with a thickness of 0.5 to 1mm on the wire groove of the iron core and the surface of the iron core. Using this method to form a...
