Default Electric brake question

Will shorting out the wiers on a PMG work as a brake like it does on an alternator?

Yes - But...
If you don't provide someplace for the current to go, you could end up burning out the windings in the generator. I would look into a big resistor that can handle the current rather than just shorting out the generator directly.

Thanks John. I was thinking of using it as a parking brake only.

A motor won't work at all as a 'parking brake' because it has to move to generate resistance-it will creep with practically no resistance at a slow speed and increase as the speed goes up.
