    en.wikipedia.org/wiki/Phase_converter

    An American Rotary Phase Converter with a Transformer. A phase converter is a device that converts electric power provided as single phase to multiple phase or vice versa. The majority of phase converters are used to produce three-phase electric power from a single-phase source, thus allowing the operation of three-phase equipment at a site that only has single-phase electrical service.

    en.wikipedia.org/wiki/Rotary_phase_converter

    A rotary phase converter, abbreviated RPC, is an electrical machine that converts power from one polyphase system to another, converting through rotary motion. Typically, single-phase electric power is used to produce three-phase electric power locally to run three-phase loads in premises where only single-phase is available.

    en.wikipedia.org/wiki/Rotary_converter

    1909 500 kW Westinghouse rotary converter. A rotary converter is a type of electrical machine which acts as a mechanical rectifier, inverter or frequency converter.. Rotary converters were used to convert alternating current (AC) to direct current (DC), or DC to AC power, before the advent of chemical or solid state power rectification and inverting.

    en.wikipedia.org/wiki/Electric_power_conversion

    Consumer voltage converters (also known as "travel converters") are used when traveling between countries that use ~120 V versus ~240 V AC mains power. (There are also consumer "adapters" which merely form an electrical connection between two differently shaped AC power plugs and sockets , but these change neither voltage nor frequency.)

    The other winding (traditionally called the field, but here both windings can be outputs) is connected to 3-phase AC power at variable frequency. This input power is adjusted in frequency and phase to compensate for changes in speed of the turbine. [4] Adjusting the frequency and phase requires an AC to DC to AC converter.

  7. Dynamo - Wikipedia

    "Dynamo Electric Machine" (end view, partly section, U.S. patent 284,110) A dynamo is an electrical generator that creates direct current using a commutator.Dynamos were the first electrical generators capable of delivering power for industry, and the foundation upon which many other later electric-power conversion devices were based, including the electric motor, the alternating-current ...

    en.wikipedia.org/wiki/Motorgenerator

    The motorgenerator set may contain a large flywheel to improve its ride-through; however, consideration must be taken in this application as the motorgenerator will lose speed and may draw a large current when power returns or the circuit-breaker is re-closed. If the speed loss is excessive (the power outage is too long), the re-closure ...

    Synchronous Rotary Converter; Motor Generator Set; Rotary Phase converter; Dynamotor; Each of the four above machines are completely different except for the dynamotor which might technically be a Motor Generator. The Synchronous Rotary Converter is a device that has a single shared rotor winding which is used to convert AC -> DC or DC -> AC.
