Problems solved by technology
[0002] The stator is the static part of the motor. The main function of the stator is to generate a rotating magnetic field. The stator of a high-permeability square motor is made of multiple silicon steel sheets that are continuously stacked and pressed together. 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 recessed with multiple wire slots for coil winding. The wire slots of the traditional high-permeability square motor stator are fully open rectangular slots. The coil winding and fixing effect is poor, which affects the quality of the finished product. The section shape of the motor stator is circular, which causes a lot of waste in the production and cutting of silicon steel sheets

The invention relates to a high permeability square motor stator which comprises a stator body. The stator body is formed by continuously stacking and pressing a number of silicon steel sheets (1). The motor stator is characterized in that the silicon steel sheets (1) are square; a through hole (2) is arranged at the center of each silicon steel sheet and four corners are rounded; eight wire grooves (3) used for winding coils are evenly arranged in each silicon steel sheet (1) on the outer edge of a through hole (2); each wire groove (3) is a semi-open rectangular groove; each corner of a silicon steel sheet (1) is provided with a mounting hole (4); and a high permeability silicon-plating layer, a water-based silicon steel sheet coating layer of 1 to 1.5 microns and an epoxy powder layer of 100 to 120 microns are sequentially arranged on the outer surface of each silicon steel sheet (1). According to the invention, the wire grooves are semi-open rectangular grooves, so that the high permeability square motor stator has a good fixation effect when coils are wound; a through hole is arranged at the center of each square silicon steel sheet, and four corners are rounded; and a lot of waste is prevented when production cutting is carried out.
