The N30 Gear Motor is a compact DC geared motor that combines a small brushed DC motor with a reduction gearbox to provide higher torque and lower rotational speed. Its compact size makes it suitable for robotics, mini RC vehicles, robotic arms, automation projects, DIY mechanisms, and Arduino-based projects.
Features
- Compact metal motor body
- Integrated reduction gearbox
- High torque at low speed
- Reversible rotation by changing polarity
- Low-voltage DC operation
- Extended output shaft
- Suitable for space-constrained projects
