Abstract

A double-column magnetic pole of a motor, including a magnetic pole body composed of multiple oriented silicon steel sheets superimposed and fixed together, each oriented silicon steel sheet is made according to the orientation direction, and each oriented silicon steel sheet is divided into large isosceles according to the geometric shape The trapezoidal outer section, the rectangular middle section and the small isosceles trapezoidal inner section are provided with a rectangular central hole on the rectangular middle section of each oriented silicon steel sheet, and the central hole divides the middle section of each oriented silicon steel sheet into It is a left middle segment and a right middle segment, a plurality of left middle segments are superimposed and fixed together to form a left magnetic pole, and a plurality of right middle segments are superimposed and fixed together to form a right magnetic pole. The double-column magnetic poles of this motor not only fully and effectively utilize the orientation characteristics of the oriented silicon steel sheet, but also optimize the magnetic conductivity, and the motor has a low sound and no squealing noise during operation, and it can also save copper wires and reduce the motor's temperature rise.

Description

technical field [0001] The invention relates to a magnetic pole of a motor, more specifically to a double-column magnetic pole of a motor. Background technique [0002] The patent No. is 200320106068.5 for the slotless motor rotor. The magnetic poles on it are superimposed and fixedly connected with multiple oriented silicon steel sheets. Each oriented silicon steel sheet is made according to the orientation direction. The orientation characteristics of the oriented silicon steel sheet are fully and effectively used, so that the magnetic conduction direction of the magnetic pole is completely consistent with the orientation direction of the silicon steel sheet, and the magnetic conduction performance is optimized. The slotless motor made of this kind of rotor has significantly improved efficiency and significantly reduced iron loss, but its disadvantage is that the motor produces strong screaming noise during operation, causing noise pollution to the surrounding environment....
