Abstract

A method for manufacturing a rotor for an electric machine with a contactless power transmission system, wherein an end winding cover is arranged on one end face of a laminated core of the rotor. The invention provides that a secondary unit (SEC) of the power transmission system is integrated in the end winding cover and, as a result, after the end winding cover has been arranged, the secondary unit (SEC) is held on the rotor indirectly via the end winding cover.
