Abstract: A rectifier diode assembly is provided and includes first and second bus bars, a diode interposed between the first and second bus bars to define first and second spaces for fluid flow between the diode and the first and second bus bars, respectively, and first and second louvers. The first louvers are compressively interposed between the first bus bar and the diode to extend across the first space for thermally and electrically connecting the first bus bar and the diode. The second louvers are compressively interposed between the second bus bar and the diode to extend across the second space for thermally and electrically connecting the second bus bar and the diode.

Abstract: An electric machine assembly includes a stator. The stator includes a core defining a rotational axis, windings assembled into the core, and a back iron heat exchanger mounted to the core, extending around the rotational axis. A plurality of coolant circuits pass from one or more coolant inlets in the back iron heat exchanger through the back iron heat exchanger, to one or more coolant outlets in the back iron heat exchanger. Between the one or more coolant inlets and the one or more coolant outlets, the plurality of cooling circuits are in fluid isolation from one another and from radially inner and outer surfaces of the back iron heat exchanger.

Abstract: In accordance with at least one aspect of this disclosure, a failure detection system for an integrated circuit component includes an integrated circuit component configured to connect to a circuit board, a first sensor operatively connected to sense and output a signal indicative of an actual current output of the component in a first state, and a second sensor operatively connected to sense and output a signal indicative of an actual condition of the component in the first state. A logic module can be configured to output a component failed state signal based at least in part on the signal indicative of the actual current output of the component in the first state and the signal indicative of the actual condition of the component in the first state.

Abstract: An electrical machine assembly includes a stator. The stator includes a core, windings assembled into the core, and a back iron heat exchanger mounted to the core. A first end plate is mounted at a first end of the core and back iron heat exchanger. A second end plate is mounted at a second end of the core and back iron heat exchanger opposite the first end plate. A coolant circuit passes from a coolant inlet in the back iron heat exchanger, through the back iron heat exchanger, into the first end plate, out of the first end plate, through the core, into the second end plate, and out of the second end plate.

Abstract: An electric machine includes a housing, a stator positioned in the housing and including a stator winding, and a rotor positioned in the housing configured to rotate about a machine axis and electromagnetically interactive with the stator across an air gap between the rotor and the stator. The rotor includes a rotor core, a plurality of permanent magnets located at the rotor core, and a rotor sleeve enclosing the rotor core and the plurality of permanent magnets. The stator is cooled via a flow of cooling oil, and the rotor is cooled via a flow of cooling air directed through the air gap between the rotor sleeve and the stator.
