Abstract
A process for fixing a rotor winding, which is hooked to connection lugs of commutator lamellas of a commutator in the vicinity between the connection lugs and winding heads that are embodied on the end face of the rotor body. In order to simplify the process, a shrink sleeve is placed over the commutator of the completed rotor and is slid onto the winding heads until the connection lugs and the connection wires of the rotor winding that extend to the connection lugs are covered. The mechanically fixed shrink sleeve is homogeneously heated with hot air while the rotor rotates so that after cooling, the shrink sleeve shrinks onto the connection lugs and connection wires as well as onto parts of the winding heads.
