Abstract
The electric machine, preferably a three-phase generator (10) for vehicles with a liquid-cooled, pot-shaped metal housing (20) includes two three-phase systems arranged in the house and situated one after the other in the axial direction, a drive shaft (13) received in the base of the metal housing on one end and in a bearing cover (18) on the drive end. For a compact connection of the two three-phase systems and exciter systems with rectifier units and regulators the electrical connections of the three-phase and exciter windings (31, 32; 14, 15) are received in the bearing cover (18) so that they are electrically connected with positive and negative diodes (44, 45) of the rectifier units arranged externally on the bearing cover (18) and with the regulators and connection terminals (22) of the machine via printed circuit boards (65, 80). The negative diodes are pressed into the bearing cover (18) and the positive diodes (45) are pressed into positive heat sinks (60), which are fastened externally to the bearing cover (18) so as to be thermally conductive and electrically insulated. For protection against dirt, moisture and the like and for the electrical connection the winding conn…
