The 130 Micro DC Motor (3V–6V) is a compact, lightweight brushed DC motor widely used in DIY toys, small robotics, and educational projects. With its classic 130-size form factor and high-speed performance, it’s ideal for building or repairing Arduino smart cars, mini gear-driven mechanisms, small fans, vibrating projects, and creative prototypes where space is limited.
This motor is a great choice for makers because it’s easy to power and control: apply DC voltage to the two terminals and it spins; reverse the polarity and it spins the opposite direction. Pair it with a motor driver (L298N, L293D, TB6612FNG, DRV8833, etc.) to control speed via PWM and direction from a microcontroller.
Key Features & Benefits
- Wide Voltage Range (3V–6V): Works with common batteries (2×AA, 3×AA, 4×AA packs, etc.)
- High-Speed Output: Suitable for fast-spinning applications and gearboxes
- Compact Size: Easy to integrate into toy housings, robot chassis, and small enclosures
- Simple Control: Two terminals for quick wiring; easy direction reversal
- DIY Friendly: Excellent for student experiments and quick prototypes
