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.
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.
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.
The motor starter is not a phase converter; it is a starter (condenzator). (The static phase converter is a special transformator). -- Robogos 13:03, 18 June 2015 (UTC) Phase converters can be, and were, used for that conversion on railways, but it's not clear what Kandó was using.
A rotary converter plant in Germany where three phase AC of 50 hertz is transformed into single phase AC of 16.67 hertz for the traction current network AC to DC plant in Baltimore, Maryland, 1910. A rotary converter plant is a facility at which rotary converters convert one form of electricity to another form of electricity. The installed ...
The Kando system of the 1930s developed by Kálmán Kandó at the Ganz Works, and used in Hungary and Italy, used rotary phase converters on the locomotive to convert the single-phase supply to three phases, as did the phase-splitting system on the Norfolk and Western Railroad in the United States.
Since rotary converters work more efficiently with lower-frequency supplies, 25 Hz was a common supply frequency for these machines. Rotary converters have been steadily replaced over the past 70 years with, at first, mercury arc rectifiers and, more recently, solid-state rectifiers. Thus, the need for special frequency power for urban traction ...
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.
