Abstract:
An electrical machine, comprising a housing; a stator mounted in said housing; a throughgoing shaft; a claw pole rotor system including a first pole ring provided with claws and a second pole ring provided with claws and mechanically connected with said first pole ring through a magnetically non conductive connecting means, said pole rings being arranged so that tips of said claws of one of said pole rings extend between said claws of the other of said pole rings; a magnetically conductive core mounted on an end side of said housing; a stationary exciter winding which is arranged on said core, said second pole ring freely rotatably surrounding said exciter winding and said core at a distance from said shaft, said mechanically non conductive connecting means being formed as a single non-magnetic plate which is arranged only at an end surface of said claw pole rotor system which faces away from said claws of said first pole ring, said claws of said second pole ring extending outwardly beyond one end side of said stator, while said claws of said first pole ring end in a region of another end side of said stator.
