    IPC: H02K1/27

    Abstract: An electric machine may include an adjacent pair of laminations each defining pockets having permanent magnets arranged therein to form magnetic poles. The laminations may be stacked in a pole-skewed fashion to form a portion of a rotor. A stator may surround the rotor. The machine may further include a separator lamination between the adjacent pair defining cutout portions having a shape based on a superposition of shapes of the pockets to increase a reluctance of leakage paths between the permanent magnets.

    Abstract: A vehicle power module assembly is provided. The vehicle power module assembly may include a multi-level housing defining first and second chambers, an inlet opening into the first chamber, and an outlet opening from the second chamber. The housing may be configured such that the chambers form a stepped manifold to influence momentum of a coolant flow between the inlet and outlet. A frame may support the housing and is located proximate to at least one power inverter. A screen may be disposed in at least one of the chambers to promote coolant flow uniformity to the outlet. The frame assembly may include a plurality of frames stacked in an array, and each frame may define a channel in at least partial registration with the outlet.

    Abstract: An active isolated circuit is provided for precharging and discharging a high voltage bus, such as within a hybrid electric vehicle, in a quick, efficient, and optimal manner. The circuit can include a battery, a DC-DC converter coupled between the battery and a main contactor, the main contactor coupled between the converter and a bus for selectively connecting the battery to the bus through the converter, and a control module for controlling the converter to selectively precharge the bus from the battery and selectively discharge the bus to the battery. The converter can be configured to isolate the battery and the bus. When a precharge signal is generated, the bus can be precharged from the battery through a transformer in the converter. The bus can be discharged to the battery through the transformer in the converter when a discharge signal is generated.

    Abstract: A vehicle power module assembly including first and second power modules is provided. The first power module may include a first lock feature extending from a lower portion of a first minor side at a first central axis. The second power module may include a second lock feature at an upper portion of a second minor side at a second central axis. The lock features may be sized for interlock with one another to secure the power modules to one another. The first lock feature may be a loop element defining a through-hole and the second lock feature may be a wedge. The through-hole may be sized for the wedge to extend therein and to interlock the first power module and the second power module to one another. The first lock feature may be a flexible hook element and the second lock feature may be a slot.
