The 411 - How Clocks (with hands) work

 

An electronic clock with hands works by using a combination of electronic circuitry and mechanical components. The electronic circuitry generates a series of electrical pulses that are sent to a small motor or stepper motor, which in turn rotates the gears and hands of the clock.

The movement of the motor is controlled by a quartz crystal oscillator, which provides a steady, high-frequency signal to ensure accurate timekeeping. The crystal oscillator vibrates at a precise frequency, usually 32,768 Hz, which is divided down to generate a one-second pulse.

The electronic circuitry then counts the number of one-second pulses and uses this information to move the gears and hands of the clock. The motor is typically attached to a gear train that reduces the speed of the motor's rotation and converts it into the slower, smoother motion required for the clock's hands to move.

The gears of the clock are arranged in a series of stages, each stage having a different gear ratio. The first stage is the fastest and is driven directly by the motor, while the subsequent stages are progressively slower and geared to drive the hour, minute, and second hands.

The hands of the clock are attached to shafts that rotate in the center of the clock face. As the gear train turns, it rotates the shafts, which in turn move the hands around the clock face. The hour and minute hands are typically driven by the same shaft, while the second hand is usually driven by a separate shaft.

An electronic clock with hands works by using a combination of electronic circuitry and mechanical components to convert electrical pulses into the smooth, continuous motion of the clock's hands. The electronic circuitry generates a steady signal, which is used to control a motor that drives a series of gears to move the hands around the clock face.
