In english Wikipedia also exists article Frequency converter, which is quite similar. Do you think that you could put these two articles together and make redirect from one of them to the second one? -- 147.230.151.146 16:10, 20 December 2006 (UTC)
How would I convert 125vac/100hz to 125vac/60hz? walterpcolar@aol.com —Preceding unsigned comment added by 69.126.31.191 ( talk) 02:40, 1 March 2010 (UTC)
There's a sort of converter that used to be common and doesn't seem to be mentioned... one consisting of a large transformer in which the secondary winding was on a rotor, and the primary the stator. The ones I knew were synchronous, driven by a smaller motor to gain 10 Hz so they could run on Australia's 50 Hz mains and produce the 60 Hz that some IBM mainframes demanded.

describes some similar machines, but wound on one shaft so that the motor was synchronous too. That's not necessary with a belt-driven system... most of the energy is going into the primary coils, so the synchronous dynamo locks on and the motor just has to follow suit.

It is mentioned that the speed of Synchronous motors depends on the frequency of the AC current, but the same applies to Asynchronous (simple AC induction motors) motors. It seems as "only synchronous motors" is implied. 79.107.34.12 ( talk) 16:15, 23 November 2023 (UTC)
