Abstract: A rotor for an electrical machine includes a rotor hub and a plurality of permanent magnet segments affixed around a perimeter of the rotor hub. In certain instances, the segments have rounded outer surfaces and form a cylindrical outer surface of the rotor when mounted to the rotor hub. Permanent magnets are selected to construct a rotor with a particular magnetic field. In certain instances, the segments include a first plurality of the permanent magnet segments and at least one multi-piece permanent magnet segment including at least two pieces, each piece having a smaller arcuate span than segments in the first plurality of segments, the magnetization direction vector of one piece different than the magnetization direction vector of at least one other piece in each multi-piece segment. In certain instances, the plurality of segments include primary magnet segments and interpole magnet segments defining two or more poles, the segments having a uniformly oriented direction vector component. In certain instances, segments in a two-pole rotor configuration have direction vector components substantially parallel and oriented in substantially the same direction.

The stator includes windings having a first set of end turns at a first end of the stator and having a second set of end turns at a second, opposing end of the stator. The stator has a substantially tubular shape and an interior lateral surface. The rotor extends through the interior of the stator. A flow inlet into a volume in the housing about the first end turns is located radially outside of the interior lateral surface of the stator. A flow outlet from the volume in the housing about the first end turns is located radially outside of the interior lateral surface. The inlet and the outlet are cooperatively arranged to communicate a flow of fluid substantially transverse across the first end of the stator.

Each coil defines a loop that extends axially through the elongate core, exits the core through an end face, and reenters the core through the end face. A first subset of the coils collectively form a first radial layer axially exterior the core and a third radial layer axially exterior the core. Each coil in the first subset resides in both the first layer and the third layer. A second subset of the coils collectively forms a second radial layer axially exterior the core and a fourth radial layer axially exterior the core. Each coil in the second subset resides in both the second layer and the fourth layer. In another aspect, an electric machine includes a stator that carries a conductive winding having multiple coils.

Abstract: An exemplary power system may include an electric machine with multiple sets of stator windings, each set of windings being coupled through a separate switch matrix to a common voltage bus, and each of which may be spatially arranged in full pitch around the stator such that stator flux harmonics are substantially reduced. The reduced stator flux harmonics may be associated with phase current harmonic content. In an example application, such power systems may operate in a generating mode to transfer mechanical energy to electrical energy on a DC voltage bus. In some illustrative embodiments, the power system may provide both high-power and high-speed (e.g., 1MW at 8000 rpm or above) motoring and/or generating capability suitable, for example, for on-board (e.g., marine, aviation, traction) power systems.
