摘要： A rotating machine assembly includes a rotating machine that has a cover that defines an outer surface of the rotating machine and a stator disposed within the cover. The stator is stationary with respect to the cover. The rotating machine also includes a shaft rotatably disposed at least partially within the cover so as to define a rotation axis. The shaft Includes a first end that is connectable to an aircraft engine and a second end that is opposite the first end. The rotating machine also includes a rotor attached to the shaft, the rotor being movable with respect to the stator and a power module including at least one MOSFET that periodically reverses an electrical current direction of the rotor. The power module includes the at least one MOSFET Is disposed within the cover.

摘要： A generator arranged to be driven by an aircraft engine, the generator comprising a stator and a rotor. The stator comprises a stator core and a plurality of slots longitudinally extending in a direction of a longitudinal axis of the stator, for receiving conductors to form windings of the stator, and a plurality of power channels. Each power channel comprises a set of windings having at least a first phase winding including a first set of coils comprising a plurality of conductors wound in a lap winding configuration, the first set of coils having a split phase belt such that the first set of coils comprises at least a first coil and a second coil, the first coil being mechanically shifted with respect to the second coil by a predetermined number of slots of the stator. The rotor comprises a permanent magnet adapted to reduce eddy-current losses.

摘要： A sensor is configured to sense the rate of change of a current in order to protect the bridge arms in a power module with power layers and measurement layers. The sensor includes at least three conductors (C1, C2, Cp) and coils. One end of each conductor is connected to a common node, while the other end of each conductor is used respectively as an electrical terminal. The at least three conductors are contained in the same plane, referred to as the primary plane, while each conductor has a plane of symmetry perpendicular to the primary plane, each plane of symmetry passing through the common node and the corresponding terminal. A first conductor and a second conductor are identical and positioned symmetrically relative to a third conductor, and at least one pair of coils is positioned symmetrically relative to a plane of symmetry.

摘要： An electrical filtering system including capacitors and an electrical distribution device including a stack of two electrically conducting layers facing one another and separated by an insulating layer, the stack being mounted on a rigid insulating plate, and said capacitors being mounted on said distribution device, the rigid plate extending in a plane orthogonal to the direction in which the layers are stacked. The distribution device includes a plurality of electrical connections distributed angularly over the outer perimeter of the distribution device and protruding in a plane parallel to the plane in which the rigid plate extends, and extending from the outer perimeter of the distribution device, each of the connections being, on the one hand, connected to at least one capacitor and, on the other hand, intended to be connected to an arm of an electrical inverter mounted on a tubular electrical converter of an electronic control unit.

摘要： A generator drive disconnect device comprising a drive transfer means (100) having a connected configuration, and a disconnected configuration. The disconnect device further comprises a disconnect mechanism, configured to move the drive transfer means from the connected configuration to the disconnected configuration, and a latch mechanism configured to the hold the drive transfer means in the disconnected configuration. The latch mechanism includes a latch member, which is moveable between a retracted position and an extended position, and a biasing mechanism. The biasing mechanism is configured to generate a biasing force to bias the latch member towards the extended position and to apply a reaction force to the latch member to resist movement of the latch member towards the retracted position, the reaction force having a magnitude which increases as a function of the distance of the latch member from the retracted position.
