Integral heat sink and fan rectifier assembly
 An integral heat sink and fan rectifier assembly comprises a disk fastened to a rotor of a synchronous motor or generator, the disk having a central bore, a plurality of fan blades disposed on the outer periphery and a circular array of recesses that receive insulation encapsulated rectifier units that are fastened to the disk and a have a heat transfer plates that engage the bottom of the recesses to transfer heat to the disk which conducts the transferred heat to the fan blades, which transfer the heat to the cooling air as rotor rotates and blows cooling air through a portion of the motor or generator.
