An apparatus for providing commutation for a direct current motor. The commutator has a magnet attached to a pivoting member and means for making and breaking at least one electrical circuit. The commutator magnet interacts with a magnet attached to the rotor. The rotor magnet can be either an independent magnet or one that also provides the motive force for causing the rotor to rotate. When the rotor magnet is adjacent the commutator magnet, the commutator changes state, thereby energizing a stator coil. The commutator has minimal moving parts and avoids the wear and maintenance problems of a conventional brush commutator.
