Abstract: An electric machine for an electrified vehicle is provided. The electric machine may include a stator, a ring plate, an encasement, and a fastener. The stator defines a cavity, a stator recess about a portion of the cavity, and a stator aperture. The stator may include windings disposed within and partially protruding out of the cavity. The ring plate may be sized for disposal within the stator recess, and may define a tab and a plate aperture for alignment with the stator aperture. The encasement may define a key sized for engagement with the tab to secure the encasement to the ring plate, and a closed coolant channel. The fastener may be sized for insertion within the apertures to secure the plate to the stator. The stator, ring plate, and encasement may be arranged with one another such that the partially protruding windings are disposed within the closed coolant channel.

Abstract: A vehicle power module assembly includes a modular manifold, an upper frame, and a plurality of power stages. The modular manifold includes a first base unit defining an inlet chamber, a second base unit defining an outlet chamber, a mid-unit defining one or more ports open to the chambers, and an upper unit defining a first set of slots and a second set of slots in fluid communication with the chambers via the ports. The plurality of power stages is housed within the frame and each of the power stages are spaced from one another to define inner channels therebetween. The chambers, channels, and ports are arranged with one another such that coolant flowing through the inner channels is in thermal communication with the power stages. The mid-unit may further include flow guides each sized to partially extend into one of the inner channels.

Abstract: In at least one embodiment, a hybrid permanent magnet is disclosed. The magnet may include a plurality of anisotropic regions of a Nd—Fe—B alloy and a plurality of anisotropic regions of a MnBi alloy. The regions of Nd—Fe—B alloy and MnBi alloy may be substantially homogeneously mixed within the hybrid magnet. The regions of Nd—Fe—B and MnBi may have the same or a similar size. The magnet may be formed by homogeneously mixing anisotropic powders of MnBi and Nd—Fe—B, aligning the powder mixture in a magnetic field, and consolidating the powder mixture to form an anisotropic hybrid magnet. The hybrid magnet may have improved coercivity at elevated temperatures, while still maintaining high magnetization.

Abstract: An encasement of an electric machine of an electrified vehicle is provided. The encasement may include a base sidewall, an inner sidewall, and an outer sidewall. The inner sidewall may extend in a circular pattern about the base sidewall. The outer sidewall may extend from the base sidewall and may be spaced apart from the inner sidewall to define a coolant channel at least partially surrounding end windings of a stator of the electric machine. The base sidewall may define features between the sidewalls to promote turbulence of coolant flowing through the coolant channel. The base sidewall may define a meandering trough between the sidewalls to form a predetermined coolant path relative to a location of the end windings.

Abstract: A vehicle power stage assembly is disclosed which may include a power stage housing, a power stage supported by the housing, and a pair of stacked DC leadframes. The pair of stacked DC leadframes are of opposite polarity and spaced apart from one another. Each of the DC leadframes may extend from the power stage and each has distal and proximal ends. The spacing between the leadframes may be such that parasitic inductances associated with current flowing through each of the leadframes at least partially cancel one another. Each of the leadframes may define a first and second side surface opposite one another. The first side surfaces may be coplanar and the second side surfaces may be coplanar. A distance between the spaced apart pair of DC leadframes may be based on a preselected amount of current and a material of the DC leadframes.
