Easy-to-stack square motor stator

Abstract

The invention relates to an easy-to-stack square motor stator, which includes a stator body, which is formed by continuous stacking and pressing of a plurality of silicon steel sheets (1). Square structure with rounded corners, eight slots (3) are evenly recessed on the silicon steel sheet (1) on the outer edge of the perforation (2), the slots (3) are semi-open rectangular slots, and the four corners of the silicon steel sheet (1) are There is one installation hole (4), and the left and right sides of the silicon steel sheet (1) are provided with auxiliary positioning edges (5) and auxiliary positioning bars (6), and the auxiliary positioning edges (5) are virtual connected to both sides of the silicon steel sheet (1) , the auxiliary positioning bar (6) is arranged in the groove of the auxiliary positioning edge (5). The wire slot of the present invention is a semi-open rectangular slot, so that the easy-to-stack square motor stator has a good fixing effect when the coil is wound, the processing method is simple, the work efficiency is high, the labor intensity of the workers is low, the overall quality is good, and the insulation effect is good.

Description

technical field [0001] The invention relates to an easily stackable square motor stator, belonging to the field of electromechanical technology. Background technique [0002] The stator is the stationary part of the motor. The main function of the stator is to generate a rotating magnetic field. The easy-to-stack square motor stator is made of multiple silicon steel sheets that are continuously stacked and pressed. The center of the silicon steel sheet is provided with a perforation to accommodate the rotor. The silicon steel sheet on the outer edge of the perforation is concave with a plurality of wire slots for coil winding. The wire slot of the traditional easy-to-stack square motor stator is a fully open rectangular slot, and the coil winding and fixing effect is poor, which affects the quality of the finished product. The cross-sectional shape of the motor stator is circular, which causes a lot of waste in the production and cutting of silicon steel sheets. SUMMARY OF...
