The present invention relates to an electrical machine including a rotor shaft, a hollow-cylindrical magnet element, a first covering disk, and a second covering disk, in which the first and second covering disks are secured to the rotor shaft, and the magnet element is secured on its first axial end to the first covering disk and on its second axial end to the second covering disk.

Rotor for an electrical machine with improved temperature stability

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.
