Some AC motors have brushes - e.g. hand drills https://en.wikipedia.org/wiki/AC_motor#Universal_motor_and_series_wound_motor
Some DC motors don't have brushes - e.g. BLDC https://en.wikipedia.org/wiki/Brushless_DC_electric_motor

Look here: https://en.wikipedia.org/wiki/Electric_motor
Then in the index on the left, look at anything with "commut..." in it.

Brushes are contact devices used to transfer power to and from a rotating object or electrical device.
There are also AC induction motors (wound rotor motor) that have brushes, the induced level in the rotor is controlled via a Slip ring (brushes) circuit.
Also a AC/DC synchronous motor.
3ph alternator. (Don't forget the generators!)
Just for a few.
