  • Rotor for an electrical machine with improved temperature stability
    Patent number: 7872388
    Abstract: 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.
    Type: Grant
    Filed: August 17, 2004
    Date of Patent: January 18, 2011
    Assignee: Robert Bosch GmbH

  • Process for fixing a rotor winding
    Publication number: 20020088108
    Abstract: In a process for fixing a rotor winding (15), which is hooked to connection lugs (122) of commutator lamellas (121) of a commutator (12) in the vicinity between the connection lugs (122) and winding heads (151) that are embodied on the end face of the rotor body (11), in order to simplify the process, a shrink sleeve (16) is placed over the commutator (12) of the completed rotor (10) and is slid onto the winding heads (151) until the connection lugs (122) and the connection wires (152) of the rotor winding (15) that extend to the connection lugs (122) are covered. The mechanically fixed shrink sleeve (16) is homogeneously heated with hot air while the rotor (10) rotates so that after cooling, it shrinks onto the connection lugs (122) and connection wires (152) as well as onto parts of the winding heads (151).
