An electric drive module having a motor and an inverter that are disposed in a housing The motor includes a stator, which has a plurality of sets of windings. The inverter has a plurality of power semiconductors, which are mounted into a retaining member, an end plate, which is sealingly coupled to the retaining member, and an inlet port that extends through the end plate. Sets of the semiconductor devices are electrically coupled to corresponding sets of the windings. Power terminals on the semiconductor devices are coupled to a heat sink. Fins on the heat sinks extend into an annular region that is adjacent to axial ends of the windings. At least one of the retaining member and the end plate is sealingly coupled to the housing assembly. The inlet port, the annular region and cooling passages in the stator are coupled in fluid communication. 1.
