Document Type and Number:
WIPO Patent Application WO/2011/095266
Kind Code:
A3
Abstract:
The invention relates to a stator of a permanently excited rotating electric machine (1), wherein a first central tooth (8a) having a first central tooth width MB is disposed in the centre of a first coil group (10a), wherein the stator (5) has a second coil group (10b), wherein the first and the second coil groups are disposed so that they directly follow one another in the circumferential direction (U), wherein a first boundary tooth (9) having a first boundary tooth width RB is disposed between the first and the second coil groups, wherein the first boundary tooth width RB is substantially RB = a ⋅ ZB and the first central tooth width MB is substantially MB = (2-a) ⋅ ZB, wherein the factor a is greater than 0 and less than 1. The invention makes it possible to reduce detent moments and/or oscillating moments occurring in a permanently excited rotating electric machine (1).
