A stator supportfor an electric machineincludes a radial cutin a support ringthat releases hoop stress in the support ringand enables more radial displacement during heating and cold soak cycles in the stator, thereby allowing a larger range of thermal conditions for the electric machine

Stator support for an electric machine

A rotor assembly () for an electric machine including a core () having at least one post () about which a winding may be wound, and a cap () coupled to the post () and having a portion overlying a winding (), wherein the cap () comprises a plurality of laminations and the core () does not comprise a plurality of laminations.

Rotor assembly for an electric machine with thermal management features

A method and disconnector for disconnecting a drive shaft of a drive mechanism from rotating equipment, upon a failure of the drive mechanism or rotating equipment, includes a housing, an arm extending from the housing and movable relative to the housing between a first position and a second position, and a parting tool on a distal end of the arm.

Method and disconnector for disconnecting a drive shaft

A method of assembling a rotating rectifier having multiple radially spaced bus bars with a corresponding fastener to an electrical machine having at least one machine with a stator and a rotor mounted on a rotating shaft, the method includes inserting the rotating rectifier into a hollow portion of the rotating shaft, axially aligning the fasteners with a corresponding radial opening in the rotating shaft, inhibiting an inward radial movement of the fasteners by inserting an inhibiting tool into an interior defined by the multiple radially spaced bus bars, and at least partially securing the fasteners to a corresponding fastener on at least one of the rotor and rotating shaft while the inhibiting tool resides in the interior.

Fastening assembly for electric machine and rectifier therefor

A rotor assembly for an electric machine includes a core having at least one post and a cap wherein electrical windings are wound about the rotor assembly to define a pole. The rotation of the rotor and rotor pole relative to a stator generates a current supplied from the electric machine to a power consuming device.

Rotor assembly for an electric machine

An electric machine, such as a generator, providing for the generation of electricity and includes a rotor generating a magnetic field and a stator having stator windings. The interaction of the magnetic field with the stator windings generates current in the windings. The generator may provide the generated current to a power output of the generator, where it may be further transmitted to an electrical load to power the load.

Stator assembly

An assembly for a gas turbine engine includes a S/G having a rotatable shaft, a main machine, a PMG, and an exciter wherein at least one of the main machine, PMG, and exciter includes a rotor mounted to the shaft and having multiple rotor poles, a stator having multiple stator poles and at least one of the rotor poles and stator poles being formed by a core with a post and wire wound about the post to form a winding, with the winding having at least one end turn, and a layer to increase cooling capabilities of a portion of at least one of the stator and the rotor.

Arrangement for cooling an electric machine with a layer of thermally conducting and electrically insulating material

A ram air turbine generator, for generating electrical power when the system is exposed to an airstream, includes a turbine having multiple blades and a rotor operably coupled to the blades and rotating about a shaft and stator mounted, such that rotation of the blades rotates the rotor, and the rotation of the rotor about the stator produces electrical power.

Ram air turbine generator with external rotor having permanent magnets

An electric machine having a rectifier assembly placed within a rotating shaft of the electric machine to convert the AC output of the electric machine to DC prior to transmission of the electricity from the electric machine.

Electric machine and rectifier assembly therefor

An aircraft starting and generating system includes a first starter/main machine assembly that includes a first exciter and a first main machine, and second starter/main machine assembly that includes a second exciter and a second main machine. The system also includes a permanent magnet generator (PMG) that is connected to the first and second starter/main machine assemblies. The system further includes a first inverter/converter/controller (ICC) that is connected to the first starter/main machine assembly and to the PMG, and a second ICC that is connected to the second starter/main machine assembly and to the PMG. The first and second ICCs generate AC power to respective drive the first and second starter/main machine assemblies in a start mode of the starting and generating system for starting a prime mover of the aircraft, and the first and second ICCs convert AC power, respectively obtained from the PMG after the prime mover has been started, to DC power in a generate mode of the starting and generating system.
