摘要：: The invention relates to an electrical machine, preferably a rotary-current generator (10) for motor vehicles, having a rectifier unit (11) on a bearing plate (23) of the machine, in which bearing plate a rotating fan (28) is disposed; the rectifier unit is secured in heat-conducting fashion to a heat-conducting annular portion (23a) of the bearing plate (23), and the annular portion surrounds a region (23b) of the bearing plate (23) that is provided with openings (27) through which the cooling air aspirated by the fan (28) flows. The negative and positive diodes of each diode bridge of the rectifier unit are disposed, with an input-side connection part inserted between them, between a common positive and negative connection plate (15, 17) and with them forms the rectifier unit.
