This video demonstrates a Lego-based lever escapement mechanism driven by two escape wheels and a magnetically regulated balance oscillator. As the escape wheels rotate, they alternately engage a pallet lever, which delivers timed impulses to a balance wheel mounted on a low-friction brass axle. The axle passes through standard Lego brick holes, offering smoother rotational movement than conventional Technic axles.
Affixed to the balance wheel is a neodymium magnet that oscillates between two stationary magnets positioned on either side. These fixed magnets are mounted on a swivel arm aligned concentrically with the balance wheel, allowing precise adjustment of the magnetic field geometry. The resulting magnetic interaction produces a restoring force that sustains periodic motion.
The escapement is tuned to match the natural resonance frequency of the balance wheel, enhancing timing accuracy and oscillatory stability. This configuration illustrates how magnetic feedback and mechanical resonance can be integrated into a compact timing system using modular Lego components.
The following playlist presents various Lego balance-wheel escapements based on magnetic repulsion and attraction for a regulated motion:
