Abstract:
An electrical machine formed as a rotary current generator, comprising a housing; a rotor rotatably supported in said housing; and a rectifier unit with MINUS and PLUS diodes which are mounted, insulated from one another, on a MINUS and a PLUS heat sink and are secured in a sandwich fashion, together with a circuit board for diode terminals, to an end region of a bearing plate, so that a lost heat of said rectifier unit is dissipatable from the PLUS heat sink which is an upper heat sink partly via a heat-conducting contact of said MINUS heat sink which is a lower heat sink with said bearing plate, and partly via at least one aspirating coolant airstream of a fan, said MINUS diodes secured in said MINUS heat sink and each having a base resting directly on said bearing plate, said MINUS diodes having pedestals which are embodied on said bearing plate and separated from one another by recesses.
