Zero Maintenance Motor Design: The Stepper Advantage

One concern with mechanical clocks is maintenance. The Xiguizi clock uses sealed, high‑quality stepper motors that require no lubrication or adjustment. Each motor drives a single telescopic segment through a lead screw or cam mechanism. Because the movement is linear and slow, wear is minimal. The stepper motor clock maintenance routine is simply: keep dust away from the tile apertures (use compressed air occasionally) and avoid extreme humidity to protect the wood casing. No gear trains to oil, no springs to replace. This makes the clock a practical long‑term purchase, not a collector’s burden.
