Processing technology of motor core

Abstract

The invention discloses a processing technology of a motor core. The processing technology comprises the following steps of 1, detecting flatness of a self-adhesive punching sheet; 2, carefully detecting a surface of the punching sheet before pasting, wherein no oil stain and dust exist in the surface, the surface is cleaned by cleaning cloth, and the cleaning cloth cannot be stained with alcohol and acetone; 3, cleaning a pasting tool; 4, inserting a positioning rod into each lamination hole, ensuring the perpendicularity requirement of a self-adhesive plate, and ensuring the punching sheet in order after adjustment; 5, hanging the pasting tool in an oil press machine; 6, placing the pasting tool in a baking oven; 7, taking the pasting tool out of the oven; and 8, detecting the flatness of an end plate, and enabling a through groove rod to smoothly pass. Compared with the prior art, the processing technology has the beneficial effects that no demagnetization is generated by the self-adhesive plate, the lamination performance of a stator core and a rotor core is achieved, the appearance quality of the self-adhesive punching sheet is ensured, the lamination coefficient of the punching sheet is ensured, the eddy-current loss of the motor is reduced, the efficiency is improved, the bonding strength of a silicon steel sheet is ensured, no demagnetization is generated by the self-adhesive plate, and the motor performance is ensured.

Description

technical field [0001] The invention relates to a processing technology of a stator and rotor iron core of a motor, in particular to a motor product suitable for a drive system of a motor of a new energy vehicle, and belongs to the field of motor and generator manufacturing. Background technique [0002] At present, the technology of the domestic new energy vehicle drive system is not yet mature, and it is generally purchased from abroad. This method of procurement is costly, and the overall price is not dominant. For manufacturers with small batch needs, the price is too high to meet the needs of customers. [0003] In foreign countries, the method of spraying glue is used as an effective process to improve the performance and reliability of new energy vehicle products in the production process of stator and rotor punching for new energy drive systems.

[0002] At present, the technology of the domestic new energy vehicle drive system is not yet mature, and it is generally purchased from abroad. This method of procurement is expensive, and the overall price is not dominant. For manufacturers with small batch needs, the price is too high and cannot meet the needs of customers.

[0003] In foreign countries, the method of spraying glue is used as an effective process to improve the performance and reliability of new energy vehicle products in the production process of stator and rotor punching for new energy drive systems. The integrated structure it gives to the product has reliable insulation performance and automation. High level and stable products, but this kind of process has high requirements on the temperature of the environment. It must be guaranteed to be -55°C--+125°C. The cost of glue spraying process is high, there is waste in the process, and the appearance quality is poor, which cannot satisfy customers with cheap and high-quality products
