Axial gap rotating electrical machine

Patent

Direct drive rotating electrical machines with axial air gaps are disclosed. In these machines, a rotor ring and stator ring define an axial air gap between them. Sets of gap-maintaining rolling supports bear between the rotor ring and the stator ring at their peripheries to maintain the axial air gap. Also disclosed are wind turbines using these generators, and structures and methods for mounting direct drive rotating electrical generators to the hubs of wind turbines. In particular, the rotor ring of the generator may be carried directly by the hub of a wind turbine to rotate relative to a shaftmore » « less

Superconducting electrical machine with two part rotor with center shaft capable of handling bending loads

Patent Morrison, Darrell

A superconducting electrical machine includes a rotor and a stator. The stator defines a cavity. The rotor is configured to rotate about a longitudinal axis. The rotor is disposed at least partially within the cavity. The rotor includes a shaft configured to rotate with the rotor, a rotor active section including at least a rotor torque tube and a superconductor, and a first re-entrant end attaching the shaft to the rotor active section. At most a threshold fraction of a bending force applied to the shaft is communicated to the rotor active section.

Method and system employing finite state machine modeling to identify one of a plurality of different electric load types

Patent Du, Liang; Yang, Yi; Harley, Ronald Gordon; ...

A system is for a plurality of different electric load types. The system includes a plurality of sensors structured to sense a voltage signal and a current signal for each of the different electric loads; and a processor. The processor acquires a voltage and current waveform from the sensors for a corresponding one of the different electric load types; calculates a power or current RMS profile of the waveform; quantizes the power or current RMS profile into a set of quantized state-values; evaluates a state-duration for each of the quantized state-values; evaluates a plurality of state-types based on the powermore » « less
