  • Permanent magnet, and electric machine comprising same, and a method for producing the electric machine
    Patent number: 9653978
    Abstract: Permanent magnet (10), containing at least one metal component (13) from the group of the rare earth metals, comprising a first coating film (20), which forms a cathodic protection against corrosion for the permanent magnet (10), the first coating film (20) containing a metal (23) which is more electronegative in the electrochemical series than the metal component (13) of the permanent magnet (10), wherein a second coating film (30), which is embodied in an electrically insulating fashion, is applied on the first coating film (20).
    Type: Grant
    Filed: March 13, 2013
    Date of Patent: May 16, 2017
    Assignee: Robert Bosch GmbH
    Inventors: Maik Zernikow, Klaus Eppel

  • Prestressed bearing for electrical machines
    Patent number: 7237962
    Abstract: The present invention relates to an electrical machine 1, in particular an electric motor, with a housing 2 and covers 3, 4 that close the housing 2 and contain bearings 7, 8 that rotatably support a rotor 5. According to the present invention, spring elements 7.3, 8.3 are provided that act upon at least one bearing shell 7.1, 7.2, 8.1, 8.2 each of bearings 7, 8 with a compression force acting in the axial direction, whereby the mounting of the bearing shell 7.1, 7.2, 8.1, 8.2 that is acted upon by one of the spring elements 7.3, 8.3 is configured as a sliding fit.
