Abstract
A pivotally oscillating motor having magnetizable armature pole elements arranged to cooperate with respective air gaps. Alternating current through a stator coil aids to the permanent magnet flux through one air gap while it reduces that in another air gap, so that alternately one or the other pole element is pivotally attracted into its respective air gap.
