Abstract: For an electrical rotating machine, it is suggested for the non-rotatable connection of a bundle of laminations with a rotor or a stator that the respective bundle of laminations have a profiled contact surface for an assigned rotor hub or an assigned stator housing, in which case, by an electromagnetic forming of the rotor hub or of the stator housing, which is effective at least in areas, its form-locking contact on the profiled contact surface of the respective bundle of laminations is achieved by plastic

Abstract: A squirrel cage rotor includes a cage, lamination sheets provided with a plurality of slots, and short circuit rings arranged at the axial ends of said lamination sheets and connected by short circuit rods disposed within said slots. In one aspect, said lamination sheets comprise sheets made of an amorphous magnetic material, especially of an amorphous metal with high saturation magnetization. In another aspect, said slots are formed with a convex base portion. In a further aspect, said short circuit rings are made of a metal matrix composite material with high electrical conductivity, preferably of a fiber reinforced aluminum matrix composite material.
