Alternators don't have brushes

Unfortunately you are wrong.

Nearly all A.C. generators, i.e. alternators, use brushes to transmit
exciting current to the rotor. The A.C. output is taken from the
stator. In the case of an automotive "alternator" the stator output is
then rectified by diodes mounted in the end plate.

The exception would be in something like a wind generator where the
rotor is a permanent magnet to avoid the cost of excition current.
