Abstract: A generator arrangement includes a stator with armature winding, a rotor with one or more permanent magnets supported for rotation relative to the stator, a variable speed drive, and a control module. The variable speed drive is connected to the rotor for rotating the rotor within a predetermined speed range. The control module is disposed in communication with the armature windings and is operatively connected to the variable speed drive to maintain constant output voltage as load changes by varying rotational speed of the rotor.

Abstract: A rotor for an electrical machine includes a rotor core having a plurality of circumferentially spaced apart rotor poles. Windings are seated in gaps between circumferentially adjacent pairs of the rotor poles. A wedge secures the windings in each gap. The wedge includes a first member made of a first material and at least one second member made of a second material. The second material has a higher electrical conductivity than the first material. The wedge is configured to supply Q-axis damping. A pair of end plates is connected electrically to the at least one second member at opposing longitudinal ends thereof thereby completing a Q-axis winding circuit for each wedge.

Abstract: A permanent magnet machine includes a rotor including a rotor hub and a plurality of permanent magnets embedded in the rotor in a circumferential pattern. The rotor includes a respective bridge between each circumferentially adjacent pair of the permanent magnets. Each bridge is of a different material than that of the rotor hub, and the rotor hub and bridges are integral with one another.

Abstract: An end winding support for an electric generator includes a pair of winding lead supports formed on opposite sides of a winding slot and separated by an upper slot width. Each of the winding lead supports includes a winding channel routed between a lead coupling port and the winding slot. The winding slot includes a base support and a pair of alignment members that define a transition between the base support and the winding lead supports. A lower slot width is defined along the base support between the alignment members and a ratio of the upper slot width to the lower slot width is between 1.024 and 1.053.

Abstract: An inductor comprises a ferromagnetic or ferrimagnetic core with a reluctance gap, a plurality of conductive windings disposed about the ferromagnetic or ferrimagnetic core, and a spacer. The spacer separates the conductive windings from the ferromagnetic or ferrimagnetic core in the immediate vicinity of the reluctance gap, such that the conductive windings are substantially unaffected by fringing flux from the reluctance gap.

Abstract: An electric machine includes a housing, a stator positioned in the housing and including a stator winding, and a rotor positioned in the housing configured to rotate about a machine axis and electromagnetically interactive with the stator across an air gap between the rotor and the stator. The rotor includes a rotor core, a plurality of permanent magnets located at the rotor core, and a rotor sleeve enclosing the rotor core and the plurality of permanent magnets. The stator is cooled via a flow of cooling oil, and the rotor is cooled via a flow of cooling air directed through the air gap between the rotor sleeve and the stator.

Abstract: A system includes a permanent magnet generator (PMG) with a generator shaft defining a longitudinal axis. A brake system includes a brake shaft with a first end operatively connected to the generator shaft for selectively rotating with the generator shaft or braking to slow the generator shaft. A shear shaft is operatively connected to a second end of the brake shaft axially opposite the first end along the longitudinal axis. The brake system includes a wedge with a first position radially withdrawn from the brake shaft, and a second position radially pressed against the brake shaft for applying braking forces to the brake shaft and to the generator shaft.

Abstract: A power supply system includes a first saturable reactor electrically connected to a first AC phase input, to a second AC phase input, and to a third AC phase input. The first saturable reactor is electrically connected to a first DC output. A second saturable reactor is electrically connected in parallel with the first saturable reactor to the first AC phase input, to the second AC phase input, and to the third AC phase input. The second saturable reactor is electrically connected to a second DC output. A reactor controller can be operatively connected to the first saturable reactor and to the second saturable reactor to regulate DC output voltage to the first and second DC outputs.
