Abstract: Methods and systems are provided for an electric axle in a vehicle. An electric axle includes an electric motor having a stator and a rotor, a coolant manifold mounted to a first end plate of the rotor, the first end plate opposite a second end plate distal to the coolant manifold, wherein the coolant manifold is configured to flow coolant to rotor coolant lines extending axially through the rotor, and a spray ring comprising coolant lines coupled to the coolant manifold, wherein coolant flowing from the coolant manifold to the spray ring flows in a direction angled to an axial direction, wherein the spray ring is positioned circumferentially about axial stator end windings and configured to spray coolant onto an outer diameter of the end windings, wherein the first end plate and the second end plate are configured to spray coolant onto an inner diameter of the end windings.

Abstract: Systems and methods for electric motor cooling. The cooling system, in one example, includes a sealing ring coupled to or formed in a stator and including a flange that axially extends outward from an axial side of the stator. The cooling system further includes a first sealing sleeve with a first sealing interface that is formed between the sealing sleeve and a motor housing and a second sealing interface that is formed between the sealing sleeve and the flange, where a cavity is formed between the sealing sleeve and the sealing ring in which a stator end winding is at least partially immersed in a coolant.

Abstract: Methods and systems are provided for a winding reconfiguration assembly for an electric machine. The winding reconfiguration assembly includes a multi-position contactor device designed to switch stator windings in the electric machine between a first electric configuration in a first position and a second electric configuration in a second position. The winding reconfiguration assembly further includes an electromagnetic actuator configured switch the multi-position contactor device between the first position and the second position in response to a change in the polarity of a coil in the electromagnetic actuator.

Abstract: Systems are provided for an electric motor. In one example, a rotor assembly of the electric motor includes a shaft, a lubricant distributor inserted into the shaft, the lubricant distributor comprising a first section comprising a plurality of first nozzles and a second section comprising a plurality of second nozzles, the lubricant distributor further comprising an overflow portion arranged between the first and second sections, and a stationary lance positioned adjacent to the first section of the lubricant distributor, the lance comprising a plurality of radial nozzles. The rotor assembly controls coolant flow towards the rotor and bearings, helping to decrease drag losses.

Abstract: A computer-implemented infrastructure providing a consistent graphical user interface that supports user-controlled organizing, storing, accessing and sharing of heterogeneous personal information of a specific user uses computer processes executed by a server system. The computer processes include receiving a set of items of information from a computing device operated on behalf of the specific user; for each item of information in the received set of items, obtaining, as a result of parsing the received set of items, new information; using the new information, and other user information stored in association with an internal account of the specific user, to produce derived information; and storing the new information and the derived information, in a storage system in communication with the server system, and associating such stored item of information with an internal account of the specific user.

Abstract: Methods and systems are provided to cool an electric machine. In one embodiment, an electric machine includes a rotor assembly that includes a rotor shaft and a stack of rotor laminations. The rotor assembly further includes one or more nozzles designed to receive pressurized coolant from a rotor shaft coolant passage and deliver the coolant to a set of open coolant channels in the stack of rotor laminations, wherein the set open coolant channels includes outlets that are profiled to direct the coolant towards a groove in a balancing plate that is coupled to the rotor assembly.
