A shaft can include a first portion comprising a first material having first material properties, a disconnect portion comprising at least some of a second material having second material properties, and a third portion comprising a third material having third material properties. The disconnect portion can be positioned between the first portion and the third portion, the three material properties being configured such that the first portion is physically disconnected from the third portion in response to failure of the disconnect portion under at least one of a mechanical load and/or an electrical load and/or thermal load.

Shaft disconnects

A wedge for use in an electric machine includes a central portion comprising at least a first material, a first wing integrally attached to the central portion, and a second wing integrally attached to the central portion opposite the first wing, wherein the first wing, and the second wing include a second material.

Composites and methods of making composite materials

An end winding support of a rotor of an electric machine is provided. The end winding support includes a first part and a second part. The first part includes an elongate body about which a conductive winding is wound. The elongate body has a surface defining a first groove. The second part is attached to the first part. The second part includes a body which extends outwardly from the elongate body and which has a surface defining a second groove corresponding to the first groove.

Two-piece end turn winding support

A generator cooling assembly is provided and includes a rotor, a generator assembly and an air-cycle machine (ACM). The generator assembly includes a generator housing, a generator housed in the generator housing and a shaft coupled to the rotor to transmit shaft power from the rotor to the generator to drive the generator. The ACM is housed in the generator housing and is receptive of air. The air is cooled by the ACM and output from the ACM to the generator as fully cooled air to cool the generator.

Generator with air-cycle cooling

A rotor assembly of a generator includes a rotor core including a plurality of core poles defining a plurality of core slots therebetween. The core poles extend from a first axial end of the rotor core to a second axial end of the rotor core. A rotor winding is installed to the rotor core and has a plurality of core segments located in the plurality of core slots, and a plurality of end turns connecting the plurality of core segments. An end plate is located at at least one of the first axial end or the second axial end and includes a plate portion and a plurality of wedge ends extending from the plate portion. Each wedge end is located at a corresponding core slot. The end plate is supportive of the plurality of end turns of the rotor winding.

Integrated wedge cooling distribution plate and end turn support

An energy storage system includes a sealed housing defining an interior space and a plurality of cells arranged within the interior space of the housing. A cooling liquid submerges each of the cells. The cooling system is positioned within the sealed housing configured to actively and passively cool and heat each of the cells.

Thermal management for electrical storage devices

A method of disconnecting a generator from a source of mechanical rotation includes receiving a generator disconnect command and receiving a rotational position of a generator input member. The input member rotational angle is compared to the target disconnect angle range, and a determination made whether to disconnect the input member from a generator drive member based on the comparison.

Generator disconnect couplings

An electric generator including: a main generator, including a rotating portion having main field windings; a stationary portion having generator armature windings; and a woven insulator at least partially enclosing the main field windings of the rotating portion, the woven insulator being included of strips or fibers of a material woven together, wherein the woven insulator is permeable to a coolant in a liquid form.

Fiber woven insulator for electric generator

An electronics cooling arrangement includes a housing, an electronic device disposed within the housing, and a solid-liquid phase change material disposed within the housing and is in thermal communication with the electronic device to absorb heat generated by the electronic device. A method of cooling an electronic device and a vehicular electronics cooling system are also described.

Immersion cooling systems and methods

An immersion cooled electronics arrangement includes a housing containing a coolant, an electronic device submerged within the housing and in thermal communication with the coolant, and a variable volume body. The variable volume body is disposed within the housing. An actuator is operatively connected to the variable volume body and is arranged to displace coolant within the housing.

Actuated immersion cooled electronic assemblies

A fixed wobbler of a hydraulic unit includes a body having a first end and an opposite second end, the first end defining a first surface, and the second end defining a second surface oriented at an angle relative to the first surface, the body having an outer diameter and an inner wall defining an inner diameter, wherein the outer diameter is approximately 2.1655+0.0000&#x2212;0.0007 inches (5.5004+0.000&#x2212;0.0018 cm), and wherein the inner diameter is approximately 1.043&#xb1;0.003 inches (2.6492&#xb1;0.0076 cm).

Fixed wobbler for hydraulic unit

A hydraulic unit includes a housing, a pump located in the housing, and a motor located in the housing and operably connected to the pump such that the motor is driven in response to fluid pressure delivered to the motor from the pump. An output shaft is operably connected to and driven by the motor and includes a body having a first end and a second opposite end, and a first flange and a substantially identical second flange integrally formed with the body of the shaft adjacent the second end. A relief is formed about a circumference of the body. A plurality of first splines are integrally formed with an exterior of the body between the second portion and the third portion, and a plurality of second splines are integrally formed with an interior surface of the body adjacent the second end.
