SPIDER Automation N20 Micro Metal Gear Motor | 3V 15 RPM | High-Torque Precision Miniature Actuator
Description
Engineered for miniature robotics, automated smart vehicles, and precise motion control setups, the SPIDER Automation N20 Micro Metal Gear Motor combines a tiny physical footprint with exceptional mechanical torque. Operating natively at 3V DC across a flexible 1.5V to 5V operational range, this compact motor features a 298:1 gearbox delivering a controlled 15 RPM no-load speed (10 RPM rated). Built with durable all-metal gears and a standard D-shaped output shaft, it is exceptionally resistant to wear and ideal for replacing damaged or sluggish motors in small appliances, custom models, and robotic platforms.
Key Features
- All-Metal Gear Train: Fine craftsmanship featuring durable metallic gears that resist wear and ensure extended operational life.
- Ultra-Compact Profile: Space-saving design with a 12 mm body diameter to fit complex, tight enclosures.
- High-Torque Output: Optimized 298:1 reduction ratio providing powerful torque (0.5 kg-cm rated, 4.0 kg-cm stall) for driving wheels and hill-climbing mechanisms.
- Flexible Power Range: Operates efficiently across a 1.5V to 5V DC voltage window with a nominal 3V rating.
- Standard D-Type Shaft: 3 mm diameter D-shaped output shaft allowing secure, slip-free mounting of wheels and gears.
Benefits
- Space-Saving Footprint: Miniature dimensions fit easily into tight robotic enclosures, model cars, and compact mechanical builds.
- Reliable Load Handling: Outstanding stall characteristics and robust torque allow small robots to navigate obstacles, climb hills, and carry heavy miniature loads effectively.
- Long-Term Durability: Premium all-metal internal gearing protects against premature stripping and mechanical wear under load.
- Easy Integration: Standard shaft configuration and lightweight build simplify mounting and mechanical coupling in DIY projects.
- Versatile Application: Perfect drop-in replacement or core drive motor for custom automation devices and educational robotics kits.
Applications
- Miniature Robotics: Compact line-following robots, hill-climbing micro rovers, and small-scale combat or utility bots.
- Smart Models & Vehicles: DIY motorized toy cars, miniature boats, and automated mechanical exhibits.
- Home Appliances & Devices: Replacement geared motors for small automated fans, compact mechanisms, and household gadgets.
- Precision Automation: Miniature pan-tilt camera drives, automated valves, and custom low-voltage mechanical actuators.
- Educational STEM Kits: Student engineering platforms and prototyping projects requiring compact motorized motion.
