    摘要: 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.

    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., 1 MW 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: 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.

According to some implementations, 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 to maintain the coils into a packed state.
