Configurations are described that provide uniform heat distribution of resistive heaters. These configurations allow successful anti-icing and deicing with relatively low applied power. One aspect involves the use of a thin film heater applied just underneath the topcoat to efficiently direct all heat to the surface, allowing anti-icing and de-icing with minimal power. This can be accomplished by employing a hybrid electrode interface, using a metal foil or metal braid that is attached to the aircraft surface with a structural adhesive that has been smoothed along the edges with metal-filled adhesive. Another aspect uses an array of heater cells created as a single sheet and a heat spreading material, provided underneath or overtop of the heater cells.

According to one embodiment, a stator includes a stator core and a stator coil configured by joining a plurality of coil segments mounted in slots of the stator core. Extending portions of the coil segments include a plurality of first extending portions, an inclined portion, and a joining end portion and a hook-shaped portion provided at an extending end of the inclined portion. The joining end portions are arranged side by side in a radial direction such that distal end surfaces are located at substantially the same height, the hook-shaped portions are meshed with each other, and a first engagement surface of one of the joining end portions faces and abuts on a first engagement surface of the other of the joining end portions.

A fluid compressor device includes a housing and a rotating group supported for rotation within the housing about an axis. The device also includes a controller for an e-machine of a turbomachine having a rotating group that is supported for rotation about an axis including a support structure, a first bus bar that is elongate and that extends about the axis, a second bus bar that is elongate and that extends about the axis, the second bus bar stacked on the first bus bar in an axial direction with respect to the axis, and a fastener arrangement that attaches the first bus bar and the second bus bar to the support structure.

An electric drive apparatus includes a rotating electric machine and a transmission. The transmission is provided, on one axial side of the rotating electric machine, integrally with the rotating electric machine. The rotating electric machine includes a stator coil that is assembled to a stator core to have first and second coil end parts respectively protruding from first and second axial end faces of the stator core. The axial protruding height of the second coil end part from the second axial end face of the stator core is larger than the axial protruding height of the first coil end part from the first axial end face of the stator core. The first coil end part is located on the same axial side of the stator core as the transmission whereas the second coil end part is located on the opposite axial side of the stator core to the transmission.

An electric machine includes a stator core defining slots and a single-layer winding disposed in the core and having first and second parallel paths. Each path includes hairpins interconnected to form a continuous circuit between a terminal and a neutral. The hairpins of the first path include a first type of hairpins each having a first leg, a second leg, a crown connecting between the legs, an outwardly extending twist joined to the first leg, and an inwardly extending twist joined to the second leg, wherein the legs are spaced apart by a span of five slots, and a second type of hairpins each having a first leg, a second leg, a crown connecting between the legs, an inwardly extending twist joined to the first leg, and an outwardly extending twist joined to the second leg, wherein the legs are spaced apart by a span of seven slots.

The present disclosure relates to a motor for a seat sliding device of a vehicle, and includes a coil module in which a plurality of first coils and a plurality of second coils are seamlessly disposed in the circumferential direction to have a cylindrical shape. Therefore, the conventional stator core having a slot and a tooth for installing the coil is not used, thereby implementing miniaturization and light-weight of a motor. and the slot and the tooth do not exist, thereby reducing a cogging torque and reducing the vibration and noise of the motor.
