Patent ID: 7786643

Claim:
An electric machine having a predetermined number of poles, the machine comprising: a rotor, and a stator having a defined number of stator slots with a stator winding which has a predetermined number of redundant winding systems with at least three phases, the number of redundant winding systems corresponding to the number of poles, wherein winding sections having an identical phase are combined to form a single phase-winding group, with the phase-winding groups being inserted in the stator slots of the poles cyclically according to their phase, wherein a slot area corresponding to the number of poles is associated with each pole and phase-winding group, wherein the defined number of stator slots corresponds to a product of the number of phases and the square of the number of poles, or an integer multiple of the product, and wherein the winding sections of a phase-winding group having an identical phase are distributed uniformly and in a predefined order over the slot positions of the slot areas associated with that phase.
