Mini 130 DC Motor – 9100 RPM Compact Power for Robotics and Arduino Projects
Building a robot and need reliable, compact motors that are easy to control? This set of 6 Mini 130 DC motors is the perfect solution. Featuring flexible 3V to 6V operation, speeds up to 9100 RPM, and a standard Ø2 mm shaft, these motors are ready to integrate with any common wheel or pinion on the market.
Note: This pack contains 6 identical motors. Wheels, pinions, and other accessories are not included. Compatible with standard 130-type motor shafts and wheels.
Why choose this model? (Key Benefits):
- 6-Piece Set — Ideal for multi-motor projects or keeping spares on hand for when you need them most.
- Up to 9100 RPM (no-load) — Provides ample speed for propellers, small fans, or lightweight propulsion systems without overheating.
- Ø2 mm × 8 mm Shaft — The industry-standard size for smart car wheels, educational robots, and common DIY kits.
- Low No-Load Current (<70 mA) — Efficient enough to run on AA batteries or USB power without draining your source in minutes.
- Compact 27.5 × 20 × 15 mm Size — Fits easily into tight enclosures or small chassis designs without requiring modifications.
- Lightweight (~17.5 g per motor) — Keeps your mobile platforms agile without adding unnecessary mass.
Performance and Specifications
The Mini 130 DC motor is a brushed DC motor widely used in educational robotics and rapid prototyping due to its simplicity and ease of control. It performs optimally at 6V nominal but runs reliably down to 3V for low-power or reduced-speed applications. With a load current under 250 mA, these motors are easily managed by popular drivers like the L298N, L293D, or TB6612FNG, ensuring your microcontroller pins remain safe from overcurrent. Speed and direction can be precisely controlled via PWM using Arduino, ESP32, or Raspberry Pi platforms with just a few lines of code.

Frequently Asked Questions
Can I connect the motor directly to an Arduino digital pin?
No. An Arduino GPIO pin typically supports a maximum of 40 mA, while the motor draws up to 250 mA under load. Please use an intermediate driver—such as the L298N or L293D—to handle the power while using your microcontroller for PWM control.
Will standard mini-robot wheels fit the Ø2 mm shaft?
Yes. The 2 mm diameter and 8 mm length are standard dimensions for smart car platforms, educational robots, and DIY kits. Most wheels and pinions available on the market are directly compatible.
What happens if I power the motor at 3V instead of 6V?
It will function perfectly. Both speed and torque will decrease proportionally, which is useful when you need lower power consumption or reduced speed without adding extra voltage-reduction circuitry.
What is the expected lifespan of these motors?
They are rated for several hundred hours of continuous operation under normal conditions—more than enough for prototypes and educational projects. To extend their lifespan, avoid prolonged stall conditions (stall current ≤ 500 mA).
Can I use these motors for a fan or a small propeller?
Yes. With a no-load speed of 9100 RPM, they are an excellent choice for small fans, drone propellers, or any mechanism requiring rapid rotation with a light load.
