3V Mini DC Generator Motor – DIY Wind Power Science Experiment
3V Mini DC Generator Motor for DIY Wind Power Experiments
Discover the magic of renewable energy with this compact 3V Mini DC Generator Motor! Perfect for students, hobbyists, makers, and educators, this tiny but mighty motor converts mechanical wind energy into usable electrical current — powerful enough to light up an LED with nothing more than a gentle breeze or a breath of air. Made in Mainland China.
Key Features
- Wind-to-Electric Conversion: Attach a fan blade, place it in front of a fan or air conditioning vent, and watch it generate electricity in real time.
- LED Compatible: Generates enough current to illuminate an LED light easily — a satisfying, hands-on demonstration of wind power generation.
- Compact & Lightweight Design: At just 24×19×22mm overall, this motor fits neatly into any DIY build, model, or science project without adding bulk.
- 1.5mm Shaft Diameter: Standard 1.5mm shaft diameter with a 10mm shaft length, compatible with a wide range of hobby fan blades and DIY model components.

Frequently Asked Questions
Q: Can this 3V mini DC generator motor power an LED light?
A: Yes! When connected to an LED and fitted with a fan blade, this mini DC generator motor can easily light up an LED. Simply place the fan blade in front of a household fan, an air conditioning vent, or even blow on it — the generated current is sufficient to illuminate the LED.
Q: Is this generator motor suitable for incandescent bulbs?
A: No. This mini generator produces a small current that is well-suited for LEDs and low-power components used in science experiments, but it does not produce enough current to power incandescent bulbs.
Q: What fan blades are compatible with this DC generator motor?
A: The motor features a standard 1.5mm diameter, 10mm long shaft, which is compatible with most hobby-grade fan blades and DIY model propellers designed for 1.5mm shafts. Fan blades are sold separately.
Q: What are the mounting dimensions for this mini generator motor?
A: The motor has 2mm fixing holes spaced 24mm apart, making it straightforward to mount securely in project frames, enclosures, or custom 3D-printed housings.
