Document Type and Number:
WIPO Patent Application WO/2014/124729
Kind Code:
A3
Abstract:
The rotor has a laminated core comprising individual sheet parts, wherein 2*p reluctance poles are formed on the individual sheet part in the circumferential direction, each pole covering an angular range, i.e. the pole pitch, wherein the angular range is 360° / (2*p), where p is the number of pole pairs and p is an integer, wherein the individual sheet part has one or more holes in each of the angular ranges, in other words each of the poles has one or more holes, wherein an identical pole is arranged opposite each pole in a point-symmetrical manner and wherein the other poles are formed differently from said pole.
