Maybe a stupid question: Would that work: create a small electric motor, mount one coil on the rotating wheel and mount another on the stand. Now put DC on fixed coil and AC would be generated on the other side (like in transformer)... Or will this not work? :-) (I am not an electrician.)
I know, I know - mechanical parts are not optimal - and also there are losses for electric motor - but the size is in question here...
- kpreid 12y agoRotary motion was used for conversion long before semiconductor devices were invented: https://en.wikipedia.org/wiki/Rotary_converter https://en.wikipedia.org/wiki/Rotary_converter I don't know what the limits on efficiency are, and the Wikipedia article mainly addresses AC-to-DC conversion rather than DC-to-AC, but I assume simply from the fact that they aren't used these days that they aren't an improvement on solid-state inverters.
