Abstract

The invention relates to a rotor and a rotor manufacturing method. The rotor (100) of a magnetoresistive motor comprises a stack (1000) with a plurality of flat rotor elements (102). Each rotor element (102) comprises a first sector element part (106) and a second sector element part (108). Two kinds of sector element parts (106 and 108) are alternately distributed around the rotation axis (104) of the rotor (100). The outer contour of each first sector element part (106) is constant from the rotation axis (104) of the rotor (100). The distance from the outer contour of each second sector element part (108) to the rotation axis (104) is shorter than the distance from the outer contour of each first sector element part (106) to the rotation axis (104). Each second sector element part (108) of each rotor element (102) is fully overlapped with one or more first sector element parts (106) of at least one other rotor element as viewed in the direction of the rotation axis, so that the protrusion part of the rotor (100) has a circular peripheral edge.

Description

technical field [0001] The present invention relates to rotors, in particular to rotors for reluctance motors, and methods of manufacture thereof. Background technique [0002] The salient pole rotor design has a simple and rigid structure, but has a low salient pole ratio leading to poor performance. The axially stacked rotor design has good saliency ratio and performance, but the eddy current loss caused by axial stacking is relatively large. However, for industrial manufacture, at least for four-pole motors, the mechanical design is extremely complex, where sheets have to be bent and bolted together. However, axially stacked two-pole motors are easier to fabricate because the electrical sheets are straight. Axially stacked bipolar structures can also be produced by explosive bonding. [0003] In practice, the transversely stacked rotor design is the best choice for industrial manufacturing, since similar sheets can be easily stamped and material loss in the rotor can b...
