Claim 0:
1. A magnetically active unit of a rotating multiphase electric machine having at least two poles, comprising:
a laminated core having a plurality of slots;
at least one winding for a respective one of the phases of the rotating multiphase electric machine, said at least one winding including at least one electric conductor forming coil groups assigned to respective ones of the at least two poles, the at least one electric conductor arranged at least partially in an electrically insulated manner in a plurality of predetermined slots of the plurality of slots of the laminated core thus forming coils of the coil groups; and
at least two sections of the at least one electric conductor of at least one of the windings arranged electrically insulated from one another in two radial layers with respect to an axis of the rotating multiphase electric machine in the plurality of predetermined slots, each layer formed by at least one of the electric conductors;
wherein at least a first one of the coil groups of one of the windings has a first number of coils which is different from a second number of coils of a second one of the coil groups of the same winding and a first number of coils of a respective one of the coil groups is different from a second number of coils of a further coil group of the same phase.
