Annealing technology of silicon steel plate for motor

Abstract

The invention discloses an annealing technology of a silicon steel plate for a motor. After early washing is carried out on the grease of a stamped plate, the stamped plate is conveyed into an annealing oxidizing furnace to carry out annealing treatment. By reasonably controlling annealing time and annealing temperature, the stress of the silicon steel plate is eliminated for restoring the original magnetic performance. Therefore, the magnetic conducting performance of a prepared iron core is improved, the efficiency of the prepared motor is increased, the temperature rise of the motor is reduced, and the cost is saved.

Description

technical field

[0001] The invention relates to a processing method for a silicon steel sheet for a motor, in particular to an annealing process for a silicon steel sheet for a motor. Background technique

[0002] At present, the requirements for high-efficiency and ultra-high-efficiency motors are getting higher and higher, and the design cost of motors is increasing, and users are not easy to accept the increase in costs, and at the same time, global resources are becoming less and less. Moreover, there is a situation where the efficiency of the motor is improved to a certain extent and cannot be improved by design. This requires other ways to improve the efficiency of the motor. To achieve low-cost high-efficiency, ultra-efficient motors.

[0003] In the prior art, the motor stamping process is as follows:

[0004] 1. Silicon steel sheet blanking;

[0005] 2. Punching the stator punching sheet and punching the rotor punching sheet shaft hole and shaft hole keyway at t...
