Specific Application of the 500 Plastic Gear Motor in Mechanical Watch Winders
The 500-type 3V plastic gear motor, with its low noise, stable speed, and compact design, serves as an ideal driving core for mechanical watch winders. Its specific applications are as follows:
1. Power and Speed Adaptation
Precise Speed (8-9 RPM): Watch winding requires simulating the natural motion of wearing a watch, typically demanding 650-1200 rotations per day (varies by brand). The motor reduces speed to 8-9 RPM (approximately 10,368-12,960 rotations per day) through its gearbox, and when paired with intermittent programming, it precisely meets the winding needs of mechanical watches without overwinding the mainspring.
Low-Voltage Safe Operation (3V): Compatible with USB or lithium battery power, ensuring stable and safe long-term operation.
2. Quiet Operation and Durability
Noise Control (≤42dB): The gearbox uses engineering plastics and precision meshing, operating almost silently to avoid disturbance during sleep or in quiet environments.
High Torque (>2.3 kg·cm): Capable of driving multi-watch rotors (e.g., dual or quadruple watch holders) smoothly, even under varying loads (e.g., different watch resistance levels).
3. Mechanical Adaptation and Installation
Output Shaft Design (7mm Diameter + Flat Side): Directly connects to the watch winder’s turntable or linkage mechanism, secured by a flat side to prevent slippage and ensure reliable transmission.
Compact Gearbox (68×50.5mm): Easily fits into the limited internal space of watch winders, with 350mm/500mm cables allowing flexible wiring.
4. Protection and Longevity Optimization
Overload Protection: The motor withstands momentary torque up to ≤7.2 kg·cm (e.g., if the turntable jams), preventing burnout, while its low power consumption (60mA under load) extends battery life.
Long-Term Durability: The plastic gearbox reduces weight (50g) and resists wear, making it suitable for 24/7 intermittent operation with a lifespan of thousands of hours.
Conclusion: The 500-type motor, with its low-speed high-torque, silent operation, and modular design, is a key component in watch winders, fulfilling the "wearing simulation" function while balancing watch maintenance needs and user experience.
