Lavet-type stepping motor of a quartz clock. A black rotor sprocket provides the mechanical output. The Lavet-type stepping motor has widespread use as a drive in electro-mechanical clocks [1] and is a special kind of single-phase stepping motor. Both analog and stepped-movement quartz clocks use the Lavet-type stepping motor (see Quartz clock).
