A commutator is an essential component in electric motors, generators, and dynamometers. Its primary function is to reverse the direction of current flow in the windings of the machine. This ensures continuous rotation in one direction in motors and converts alternating current (AC) to direct current (DC) in generators.

DC tachometer generator; AC tachometer generator. These type of tachometers consists of ac or dc generators that convert the rotational or angular speed into dc or ac voltage. The electrical voltage developed in the conductor is due to the relative perpendicular motion between the magnetic field and the conductor.

One of the drawbacks of this kind of AC motor is the high current which must flow through the rotating contacts. Sparking and heating at those contacts can waste energy and shorten the lifetime of the motor. In common AC motors the magnetic field is produced by an electromagnet powered by the same AC voltage as the motor coil.
