STATOR OF A PERMANENTLY EXCITED ROTATING ELECTRIC MACHINE

摘要

The invention relates to a stator of a permanently excited rotating electric machine, wherein the stator comprises a plurality of segments disposed adjacent to one another in the circumferential direction of the stator, wherein the segments have teeth and grooves extending in the axial direction of the stator, wherein segments which immediately adjoin one another are in contact with one another at a segment boundary, wherein the teeth of the segments which immediately adjoin one another are disposed such that at the segment boundary one tooth of one segment is in contact with one tooth of the segment immediately adjoining the one segment, wherein the sum of the widths of the two teeth which are in contact at the respective segment boundary is greater than the uniform width of the majority of teeth which are not disposed immediately at a segment boundary, or of all teeth which are not disposed immediately at a segment boundary. The invention makes it possible to reduce detent moments and/or oscillating moments occurring in a permanently excited rotating electric machine.
