Abstract

The invention, which belongs to the magnetic circuit component field of the motor, more particularly relates to a method for preparing a high-performance stator iron of an amorphous alloy, wherein the stator iron is used for a motor. The method comprises the following steps: carrying out lateral shearing on an amorphous strip to obtain a plurality of amorphous slices with the same shape; carrying out stacking, compaction and clamping on the amorphous slices, carrying out cutting wholly, and then carrying out mechanical fastening along a stator shaft; and carrying out whole annealing processing on a complete amorphous alloy iron core. According to the method, the mechanical fastening is used to replace adhesion fixing among the amorphous slices to solve problems that interlaminar fracture occurs frequently with utilization of the interlaminar adhesion method and the iron core performance is reduced due to the existence of the adhesion stress, thereby further substantially improving the performance of the stator iron core of the amorphous alloy.

Description

technical field

[0001] The invention belongs to the field of magnetic circuit components of motors, and in particular relates to a method for preparing a high-performance amorphous alloy stator core for motors, and the stator core is especially suitable for high-frequency motors. Background technique

[0002] At present, more and more application fields put forward higher requirements on the performance of motors, such as aerospace, electric vehicles, robots, high-speed compressors, high-speed flywheel energy storage, turbomolecular pumps, high-speed machine tools, high-speed infrared scanners, high-speed Applications such as centrifugal separators not only require the motor to have high power density or high speed, but also require the motor to have high efficiency at the same time.

[0003] We know that to achieve high power density or high speed of the motor, the frequency of the motor must be increased. However, with the increase of the frequency of the motor, the core l...
