Abstract

An electrical machine, specially a three-phase alternator of the claw pole type for motor vehicles, has its rotor system joined to the machine shaft by a noise absorbing intermediate layer. The pole pieces and the magnetic core are joined by a central sleeve to a prefabricated unit which is pressed over the intermediate layer on the shaft. The preferred material for the intermediate layer is a thermally stable plastic such as a polyurethane elastomer (VULKOLLAN, RTM). This eliminates both the axial and the radial vibrations at the source.
