A rotor for an electric machine includes a rotor yoke having a plurality of axial winding slots distributed on an outer periphery of the rotor yoke; a winding bar disposed in one of the plurality of axial winding slots, the winding bar having at least one winding end emerging axially from the rotor yoke so as to form an end winding; and a retaining device including a plurality of radial bolts, each of the plurality of radial bolts having a head fixedly connected to a shank, wherein the retaining device retains the end winding against a centrifugal force acting on the end winding.

Rotor for an electric machine having a retaining device for the end winding

A rotor for an electrodynamic machine includes a laminated core having a plurality of lamination segments arranged in series in an axial direction, wherein the laminated core includes cooling ducts formed by duct spacers disposed between axially adjacent lamination segments, wherein the duct spacers are configured to resist centrifugal forces acting on the duct spacers and are supported by axial bolts extending through the laminated core in the axial direction.
