Abstract

The invention discloses a winding type skewed slot motor iron core, and relates to the field of rotating motor iron cores and manufacturing thereof. The winding type skewed slot motor iron core is formed by spirally winding and superposing multiple layers of material strips, wherein the material strips are connected in a fixed connection mode, the inner side surfaces of the layers of the iron corebody are aligned, and a slot opening of the iron core body is a skewed slot. The method for manufacturing the winding type skewed slot motor iron core comprises the steps of 101, pre-processing a material strip; 102, processing the material strip; 103, winding the material strip; and 104, integrally forming the material strip. The winding type skewed slot motor iron core designed by the inventionhas the advantages that the two end faces of the iron core are relatively flush, the number of processing procedures is small, and the material utilization rate is high.

Description

technical field [0001] The invention relates to the iron core of a rotating electrical machine and the field of manufacturing thereof, in particular to a winding type inclined slot electrical machine iron core, a manufacturing method thereof and a rotating electrical machine comprising the iron core. Background technique [0002] The motor core chute can improve the magnetic circuit and weaken the high-order electromagnetic harmonics, so as to achieve the effect of smooth motor waveform, reduce its noise and vibration, reduce loss and improve efficiency. Therefore, the motor core chute technology is one of the most extensive and effective methods to suppress the cogging torque ripple. [0003] At present, the production methods of chute motor cores are generally divided into spiral chute and translation chute. Both of these methods are punched out of a single silicon steel sheet by stamping and then laminated to form or use high magnetic permeability core materials. Made in...
