摘要： 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.

摘要： In one aspect, a stator core for a stator of an electrical machine includes an elongate stator yoke having an interior surface that defines an axial central opening through the stator yoke. The interior surface further defines a plurality of axial channels about a perimeter of the central opening. A plurality of stator teeth are retained in the plurality of axial channels and spaced apart from one another to define to define axial channels to receive windings of the stator.
In another aspect, a stator includes an elongate core defining an inner volume to receive a rotor of an electric machine. The core includes a yoke and an array of teeth extending from the yoke toward the inner volume. The array of teeth defines slots between each pair of adjacent teeth in the array. Each slot includes a first slot region adapted to hold at least a portion of a conductive winding and a second slot region adapted to hold at least a portion of a conductive winding. The first slot region is defined by two non-parallel opposing slot side portions, and the second slot region is defined by two parallel opposing slot side portions.
In another aspect, an electric machine may include a central opening and a plurality of teeth facing inwardly toward the central opening. Slots may be defined between adjacent teeth, and a wedge may be disposed in one or more of the slots, partitioning the slots into a coils portion and an open portion. A gap may be defined between the stator core and the rotor. A fluid flow path defined from the gap and the open portions of the slots provide for improved fluid flow through the electric machine. Wedges disposed in the slots maintain the coils into a packed state

摘要： In one aspect, a stator for an electric machine includes multiple conductive coils. 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. A first subset of the coils are in a first configuration, and a second subset of the coils are in a second configuration. In some implementations, the first configuration is a lap winding configuration, and the second configuration is a concentric winding configuration.

摘要： An electrical machine includes a stator and a rotor disposed in a housing of the electrical machine. 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.

摘要： A system may include a drive driving a machine. The machine may include a stator having different winding locations distributed evenly across its surface, and a number of coils arranged symmetrically among the winding locations and connected to form N sets of multiple (M) phase windings. For each winding, each corresponding coil may span a single pole to form a full pitch winding. Each winding may be offset with respect to each other to reduce a harmonic content of a magnetic flux within certain frequency range during operation. The drive may include a processing stage that includes N independent modules corresponding to each winding. Each of the N modules may have M output ports for connection to each corresponding winding. Each of the N modules may be powered by a direct current power source, and have an M number of switch matrices that have at least three levels of output.
