いる。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electric machine, in particular a motor vehicle, having a contact device for a rotor winding and a contact device holder which is fixed coaxially in a central bore of the rotor shaft end. This invention relates to a rotor for a three-phase generator. Such a rotor for electric machines is described, for example, in Japanese Utility Model Application No. 50-117305, but in this case the contact device is constructed by attaching a number of slip rings to a plastic molded body, and the contact device is constructed by attaching a number of slip rings to a plastic molded body. A coaxial cylindrical protrusion is inserted into an axial hole at the end of the rotor shaft and fixed by adhesive. The connecting wire between the contact device (slip ring) and the rotor winding is embedded in the plastic molding.

維持しなければならず、接着工程は大量生産の場
合好ましくない。 In such known rotors, due to the large volume of the plastic, heat is not sufficiently removed, which results in mechanical stresses. Furthermore, the cylindrical protrusion is subjected to strong bending and shearing forces due to the force acting on the slip ring from the carbon brush. Furthermore, in order to insert and glue the cylindrical projection into the bore of the rotor shaft, fairly small tolerances have to be maintained, making the gluing process undesirable for mass production.

Also, the thin walls of the insulation and the clamping sleeve of the contact device ensure that heat is removed from the slip ring. Furthermore, there is no need to embed the connecting conductor in plastic or the like.
