Patent number: 7154204Abstract: A rotor for an electric motor having a short-circuit element that has lamination packets in which the laminations of the short-circuit element are embodied with spring elements which press from two sides against permanent magnets of the rotor and as a result center the permanent magnets in the lateral direction independently of production tolerances. After the insertion of the permanent magnets between the spring elements, the short-circuit element with the permanent magnets is potted, for instance with synthetic resin, or spray-coated with plastic. The rotor has the advantage that it compensates for production tolerances of the permanent magnets.Type: GrantFiled: December 18, 2002Date of Patent: December 26, 2006Assignee: Robert Bosch GmbHInventor: Tilo Koenig
