How Closed-Loop Calibration Solves Mechanical Clock Error Forever

The biggest fear for buyers of mechanical clocks is time drift. Without feedback, traditional stepper motors suffer from misalignment over long periods. Hangzhou Xiguizi’s Mechanical Digital Clock incorporates a novel control method that utilizes a “closed-loop position calibration” logic. While commercial patents often rely on open-loop control that counts steps and hopes for the best, this system uses sensor feedback to confirm the exact status of each telescopic segment (whether it is extended or retracted). This solves the critical issue of “cumulative error.” If an external force disrupts the segment position (e.g., during cleaning), the system automatically initiates a recalibration process upon the next time sync. By integrating wireless WiFi time calibration technology, the clock resets its mechanical position against the atomic internet clock.
