No AC motors don't use brushes. This is the simple diagram of AC induction motor. Here the two pair of electromagnet i.e blue and red are connected to a AC source (not shown in figure), the two pairs of electromagnets are carrying alternating current of same periodicity but different phase difference. read more

There are at least three types of AC motors that use brushes on the armature, Synchronous, wound rotor induction motor for low speed/torque control used on cranes etc and Universal AC/DC series connected motor, I would say you have the latter, if it is on a band saw. These motors are used in everything from vacuum cleaners to power tools etc. read more

A brush is a device which conducts current between stationary wires and moving parts, most commonly in a rotating shaft. Typical applications include electric motors, alternators and electric generators. read more
