摘要： Techniques and methods related to a multi-mode operation of a synchronous electrical generator. The synchronous generator is configurable in at least two modes: a grid-power mode and a power-generation mode. In the power-generation mode, electrical power is generated in response to power produced by a prime mover. In the grid-power mode, the rotor is in standstill mode, and the configurable rotor winding is configured to generate a plurality of AC magnetic fields. The system provides for seamless transfer of power between grid-power to power generation using an energy storage unit and associated power conditioning apparatus.

摘要： A rotating electric machine includes a rotor and a stator. The stator includes a stator core and a stator coil. The stator coil includes three first windings, three second windings and three switch units. The first windings are Δ-connected to define three nodes therebetween. The second windings are arranged so as to be respectively connectable between the nodes and three phase terminals of the stator coil. The switch units respectively switch the connections between the nodes and the phase terminals between a direct connection state and an indirect connection state. In the direct connection state, the nodes are respectively directly connected with the phase terminals. In the indirect connection state, the nodes are respectively connected with the phase terminals via the second windings. The first and second windings are mounted on the stator core so that the first windings are located closer than the second windings to the rotor.

摘要： A multi-speed electric motor may include a plurality of windings arranged into winding phase groups. A speed controller may switch two or more windings between a series and a parallel configuration in each winding phase group. The speed controller may also switch the winding phase groups between a delta and a Wye configuration. By selecting a specific configuration, one or more of the holding torque, torque ratio, no-load maximum speed, and volts/Hz ratio of the AC motor may be optimized for a given application. In some embodiments, the AC motor may be used as part of a piece of drilling rig equipment such as a drawworks, winch, mud pump, top drive, or rotary table.
