    摘要： An electrical power system may comprise a main generator with a rotor having field windings and at least one embedded permanent magnet. A generator control unit (GCU) may be connected to receive excitation current produced by the main generator with flux from the at least one permanent magnet. An exciter generator may be connected to be provided with excitation from the GCU. The exciter generator may provide excitation current to the field windings of the main generator. The main generator may produce output current from flux from the field windings and the at least one permanent magnet.

    摘要： A generator system is configured to supply relatively constant frequency AC power when driven by a variable speed prime mover, by independently controlling the main rotor flux rotational speed. The generator system includes an exciter stator that induces current in the exciter rotor windings at a desired frequency and phasing. The exciter rotor windings are electrically connected to the main rotor windings, and are thus electrically excited at the same frequency and phasing. Excitation is supplied to the exciter stator from an exciter controller, which controls the frequency and phasing of the exciter excitation, based on the rotational speed of the generator, to maintain a constant output frequency.

    摘要： A shear gear arrangement with gear teeth on the bearing liner positioned to engage complementary teeth on a shear gear main body. The bearing liner is static, while the shear gear main body mounts on the rotating drive shaft. If a failure occurs, the drive shaft displacement causes the shear gear main body gear teeth to engage the bearing liner teeth, instantaneously loading the shear section of the shaft with a sufficient torque load to shear the section as designed.

    摘要： An electrical motor or generator asymmetrical armature winding configuration generating a multi-phase balanced power output. Each winding group for each pole, and the conductors constituting each winding group, are chosen individually according to their magnetomotive force (MMF) vector relationship to provide a balanced power output even though the individual windings may not be balanced or symmetrical.

    摘要： A system is provided for cooling a stator coil of a rotating machine. In one embodiment, and by way of example only, the system includes a stator core, a radial core opening, and a sleeve. The stator core has an axially extending slot formed therein, an outer circumferential surface, and an inner circumferential surface. The radial core opening extends from the stator core outer circumferential surface to the axially extending slot. The sleeve is disposed within the axial slot and configured to surround the stator coil. The sleeve has a cooling fluid supply port formed therein that is aligned with the radial core opening.
