This third version of the Lego-based clock escapement demonstrates improved timing regulation through magnetic feedback and mechanical tuning. The balance wheel is fitted with 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 impulse transfer point and magnetic field symmetry.
The system is designed to regulate the escapement cycle by synchronizing the magnetic restoring force with the natural resonance frequency of the balance wheel. This harmonic tuning enhances oscillatory precision and stability. The balance wheel rotates on a low-friction brass axle inserted through standard Lego brick holes, offering smoother motion than conventional Technic axles.
Special thanks to @BenVanDeWaal for contributing valuable analysis and recommendations that led to refined magnetic alignment and improved performance in this iteration.
