  • Device for electrical coupling of generator and exciter rotor current leads
    Patent number: 4014599
    Abstract: A device for electrical coupling of generator and exciter rotor current leads, made in the form of flexible busbars located in the area of mechanical coupling between said rotors, characterized, according to the invention, in that the end face of the shaft of one rotor is provided with a projection under which said flexible busbars forming an overlapping joint are placed parallel to the shaft axis, said busbars being attached to said projection by means of a clamp embracing said busbars and projection in the cross-sectional plane of the shaft.The present invention relates to electric machines, and more particularly, to devices used for electrical coupling of generator and exciter rotor current leads.Known in the art are devices, wherein the coupling between the generator rotor current lead and the exciter rotor current lead is effected by means of spring-loaded contacts, the contact surfaces whereof are located in a plane normal to the shaft axis.
