Abstract
The invention relates to an electric machine comprising a stator, this stator comprising a set () of magnetic laminations which is made up of at least one first subset () and of at least one second subset () adjacent to the first the laminations of the first and second subsets having parts which become superposed, each comprising at least one closed channel formed within the laminations, the laminations being identical but angularly offset from one another by an angle 360°/n about the axis of the machine, where n is a non-zero integer, the laminations being without symmetry in a rotation by 360°/n so that the parts of the laminations thus offset which become superposed are nonidentical and create the said perturbation in the flow at the transition between the channels of the first and second subsets.
