Power supply bus between a coiled rotor and a contactless excitation system

Abstract

Power bus (4) for an electric motor of a motor vehicle, said bus being intended to be interposed between a ball bearing (6) and a mechanical shaft (5) of the electric motor. It comprises a distal end (9) having means for connecting the power bus with a non-contact excitation system (3) of a wound rotor (2) of an electric motor, a proximal end (10) having means for connecting the power bus with a wound rotor (2) of an electric motor, one or more arms (11, 12), and electrical wires (13) inserted into axial passages formed in the arms (11, 12), enabling electrical contact to be established between said non-contact excitation system (3) and said wound rotor (2). Figure for the abbreviation: Fig 1
