Abstract

The invention relates to a processing method of an amorphous alloy stator core slot, which comprises the steps of: making a special locking and positioning clamp used for processing the amorphous alloy stator core slot; packing a stator core to be processed into the locking and positioning clamp for repeatedly positioning and fixedly locking the stator core; and milling a batch of stator core cable embedding trays after each time of positioning and fixedly locking until finishing all the cable embedding trays of the stator core to be processed. The processing method of the invention has the advantages of high efficiency, stable quality, low cost and the like, eliminates the problems of cracking and falling-off of the edge of the amorphous alloy stator core, caused by the impact of cutting force in a traditional mechanical processing method, and also avoids the problem on affecting processing due to nonconductive phenomenon caused by insulation of an adhesive in wire cutting. The invention also relates to the locking and positioning clamp used for processing the amorphous alloy stator core slot.

Description

【Technical field】 [0001] The present invention relates to the components of the magnetic circuit of the motor and its manufacturing method, in particular to the manufacturing method of the stator body of the motor, and in particular to the processing method of the stator core embedding slot made of amorphous alloy material, and the present invention also relates to the Locking and positioning fixture in the process of stator core embedding groove processing. 【Background technique】 [0002] Most of the traditional generators and motors use silicon steel laminations as the stator core. The resistivity and magnetic permeability of silicon steel laminations are low. When the motor runs at high speed, the eddy current is serious, resulting in large iron loss, especially in high frequency motors. Larger, resulting in reduced performance of the motor due to high temperature rise, and shortened motor life; this type of motor generally cannot be used at a high frequency of several ki...
