Drive system e.g. for vehicle, has rotor arrangement connected to drive shaft via bearer arrangement with bearer section of lower permeability than at least one part of rotor interaction region

摘要

The drive system has an electric machine (14) for driving the drive shaft (12) of a drive unit and/or for deriving electrical energy when the shaft is rotated, with a stator (18) and rotor (22) arrangement. The rotor arrangement is connected to the drive shaft via a bearer arrangement (98) for a rotor interaction region (92). The bearer arrangement has a bearer section (96) of lower permeability than at least one part of the rotor interaction region.
