A cooling device for a power module having an electronic module disposed on a base plate via a substrate is disclosed. The cooling device includes a heat sink plate having at least one cooling segment. The cooling segment includes an inlet plenum for entry of a cooling medium, a plurality of inlet manifold channels, a plurality of outlet manifold channels, and an outlet plenum. The plurality of inlet manifold channels are coupled orthogonally to the inlet plenum for receiving the cooling medium from the inlet plenum. The plurality of outlet manifold channels are disposed parallel to the inlet manifold channels. The outlet plenum is coupled orthogonally to the plurality of outlet manifold channels for exhaust of the cooling medium. A plurality of millichannels are disposed in the base plate orthogonally to the inlet and the outlet manifold channels. The plurality ofmilli channels direct the cooling medium from the plurality of inlet manifold channels to the plurality of outlet manifold channels.

An electrical machine comprising a rotor is presented. The electrical machine includes the rotor disposed on a rotatable shaft and defining a plurality of radial protrusions extending from the shaft up to a periphery of the rotor. The radial protrusions having cavities define a fluid path. A stationary shaft is disposed concentrically within the rotatable shaft wherein an annular space is formed between the stationary and rotatable shaft. A plurality of magnetic segments is disposed on the radial protrusions and the fluid path from within the stationary shaft into the annular space and extending through the cavities within the radial protrusions.

Rotor and stator assemblies that utilize magnetic bearings for supporting the rotor shaft during operation can be suitably used in corrosive environments, such as sour gas. The rotor and stator assemblies include NACE compliant magnetic bearing arrangements for sour gas applications. In one embodiment, a rotor shaft assembly (100) for a magnetic bearing arrangement comprises a rotor shaft (102) formed of a ferromagnetic material comprising a plurality of rotor laminations (104) disposed on the rotor shaft (102); and a barrier layer (106) formed on selected exposed surfaces of the rotor shaft 102, wherein the barrier layer (106) is effective to resist corrosion relative to the surface without the barrier layer (106).

A synchronous reluctance machine (10) that has a stator (11) and a rotor shaft (59) operationally disposed within the confines of the stator (11). Laminations (18 to 29, 39) are axially stacked to form boat shaped segments. A plurality of selected boat shaped segments form a selected number of rotor poles (14, 15, 16, 17) about the rotor shaft and a plurality of support bars (30, 43, 44) disposed intermittently between the boat shaped segments. Each segment of lamination is boat shaped with angular acuity facing towards the stator.
