ROTOR DEVICE OF AN ELECTRIC MACHINE, IN PARTICULAR FOR A TRACTION DRIVE OF A MOTOR VEHICLE

A rotor device, including a rotor having at least one rotor laminated core and drum radially enclosing the rotor. Magnetic units including inner and outer magnetic units are embedded in the rotor laminated core. The inner magnetic units are each arranged between at least one inner and intermediate sheet metal element. The outer magnetic units are each arranged between at least one intermediate and outer sheet metal element. Flux barriers extend along the magnetic units. At least one inner, intermediate, and outer sheet metal element are mechanically held together by the at least one drum. The at least one intermediate sheet metal element is fixed to the at least one inner sheet metal element by fixation bars in an area of the flux barriers. Each of the at least one outer sheet metal elements are fixed to the at least one intermediate sheet metal element by the fixation bars.
