Zusammenfassung:	An oscillating motor for a personal care appliance that aims to reduce or substantially eliminate vibration transmitted to the appliance handle. In order to reduce vibration in the handle, the oscillating motor in one embodiment includes dual workpiece mounts. Each workpiece mount is moved independently by one of the two output drives or armatures of the oscillating motor. The oscillating motor utilizes dual, counter-oscillating armatures, each armature/inertial device being configured to offset the inertia generated by the other of the armature/inertial device, thereby creating zero or almost zero moments about the oscillating axis of the workpiece.
