Abstract: An electric machine configured to propel a vehicle includes a stator, a rotor, and an end plate. The stator has end windings that protrude axially therefrom. The rotor is disposed within the stator. The end plate is secured to an axial end of the rotor. The end plate defines a primary chamber, a secondary chamber that is radially outward of the primary chamber, and a first outlet channel that is configured to direct fluid onto the end windings. The primary chamber is in fluid communication with a fluid source and the secondary chamber. The secondary chamber is in fluid communication with the outlet channel.

Abstract: Power modules of a power module assembly each have a power card including a substrate, signal pins, and power terminals, and a casing over molded on the power card to define a passageway extending between opposite ends of the power module, and a continuous uninterrupted thermal path from the power card to the passageway. The modules are arranged end-to-end to define a continuous fluid pathway via the passageways.

Abstract: A vehicle includes a controller programmed to, responsive to injecting a high frequency voltage signal to an electric machine, determine an estimated negative sequence current phase associated with an electric machine current, and responsive to a rotor of the electric machine being at a predetermined rotor position, inject a pulse torque command to the electric machine and observe a speed change of the electric machine to determine a cable sequence.

Abstract: An electric machine includes a stator core defining slots having radial layers that each include adjacent first and second pin positions. Pins are disposed in corresponding ones of the slots and are interconnected to form a winding path. The path occupies the first and second positions of each layer, and, for each of the corresponding slots, the pins are in a same layer.

Abstract: A vehicle power module assembly including an array of stacked switch unit assemblies, a front cover, first and second side rails, and an end cover is provided. Each of the assemblies may include a power stage frame having a mid-cutout located at a substantially central side frame region such that a mid-cutout region is defined along each side of the array. The front cover may be disposed at a first end of the array. The first and second side rails may each extend from the front cover and each may be disposed within one of the mid-cutout regions such that an outer surface of each side rail is substantially flush with an outer surface of a respective power stage frame. The end cover may be arranged with the front cover to retain the assemblies therebetween. The assembly may further include a clamping plate and a spring element.

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.

Abstract: A rotor for a permanent magnet machine includes a first and second stack of same laminations. The laminations are configured to rotate about an axis and define poles and axial grooves on a circumferential surface that are asymmetric about a centerline of each of the poles. The stacks are coupled such that the second stack is flipped relative to the first stack and centerlines of the first stack are aligned with centerlines of the second stack.

Abstract: An electric machine having a rotor is disclosed. The rotor defines a cavity containing a magnet, an outer periphery, and a top bridge therebetween that includes at least two slots each having a length in a radial direction. A maximum of the lengths is closest to a Q-axis and a minimum of the lengths is closest to a D-axis. As the electric machine is operating, a rate of change in airgap flux density through the top bridge differs.

Abstract: In hybrid electric vehicles having increased battery storage capacity and plug-in capability, electric-only operation of significant duration is available. To supplement lubrication for the electric and mechanical components provided in a fluid circuit by an engine-driven mechanical pump, an electric pump is provided in parallel to the mechanical pump. When the electric pump is operating, a diagnostic can be performed to determine system integrity. According to one embodiment, an actual quantity provide to the circuit is determined; an expected quantity is estimated; and a fault is determined when the actual and expected quantities differ by more than a predetermined amount. The fault may indicate a leak or plug in the fluid circuit or a failure of a component in the fluid circuit.

Abstract: A vehicle power supply includes a housing, a backing plate, a power assembly, and a clamp. The housing has a bottom wall and a side wall. The backing plate extends from the bottom wall. The power assembly has an array of electrical switching units that extend from the side wall to the backing plate. The clamp extends from the backing plate and is configured to engage a backside of the array such that a frontside of the array is forced into engagement with the side wall.
