Abstract
Abstract The specification discloses an electronic clockwork drive in which an oscillator, which is oscillatable relative to a stationary coil, has two circumferentially spaced magnet systems, each comprising two circumferentially spaced respectively oppositely polarized magnetic axes and each having an airgap. As the oscillator oscillates, each magnet system induces actuating voltage pulses in the coil when the respective magnet system is substantially centered over the coil and moving in a respective direction. The voltage pulses induced in the coil actuate a coil energizing circuit to supply a pulse of current to the coil, which delivers a drive impulse to the oscillator. Each magnet system thus develops a single drive impulse on the oscillator during each period of oscillation of the oscillator.
