Commutator Design . A commutator is a rotary electrical switch that periodically reverses the current between the rotor and the external circuit. A steady, rotating force (torque) is produced by reversing the current direction in the moving coil of the motor's armature.

The commutator enters when the rotor has turned about 120°, and reverse the connection from the supply to the armature. It is also shown that thermal forces acting circumferentially create a requirement for interbar insulation which is both strict and to some. Brushless dc motors also require commutation, but for brushless designs.

Early machines used brushes made from strands of copper wire to contact the surface of the commutator. If the armature has multiple coils, the commutator will similarly have multiple segments—one for each end of each coil. In motors, commutators apply power to the best location on the rotor. The brushes and commutator are therefore a weak point in the traditional.
