ROTOR OF AN ELECTRIC MACHINE, AND ELECTRIC MACHINE

摘要

A rotor of an electric machine includes a rotor lamination stack connected to a rotor shaft for conjoint rotation therewith. The rotor lamination stack extends from a first axial face of the rotor lamination stack to a second axial face when viewed in the direction of an axis of rotation of the rotor lamination stack. The rotor lamination stack has bores distributed around the axis of rotation and extending from the first axial face to the second axial face. A tie rod which protrudes from the axial faces when viewed in the direction of the axis of rotation is inserted into each bore. Fastening elements are attached to the tied rods at both axial faces so that the rotor laminations of the rotor lamination stack are pressed together. A fan is attached to the tie rods on the first axial face of the rotor lamination stack.
