Modifying automotive alternator windings...

[Externet]

What to expect if the three windings in a plain automotive alternator are rewired to a series connection ?
Would it yield higher frequency single phase ?
Would the output yield higher DC voltage after a bridge rectifier ?
Would it release the smoke if windings get paralleled instead ?

Automotive alternators have three windings connected in a Y or Delta configuration.
Y gives higher voltage at low speeds, and Delta has higher current output.

I guess that you could join the starts and finishes of each winding in the correct sequence to get a higher voltage single phase output.
Current output would be heavily reduced.
Would be trial and error with possibly a bit of smoke release on the error attempts?

Would to care to add why?
Just most times it helps to add alternatives or whatever.

Connecting the windings in series will not produce smoke. The current will be the same in each winding..

Take a piece of paper and draw three lines at 120 degrees from each other. Make three pieces of paper with the angles retained. Move these pieces end to end to see the resulting total voltage.

The windings cannot be connected in parallel since the phases will not be identical. Smoke can be produced.

The frequency depends on the rotating speed and the number of poles.
