Frequently Asked Questions

Q: What is the output voltage range of this three-phase AC brushless generator?

A: This mini brushless generator outputs between 3V and 24V DC (after rectification), with a current range of 0.1A to 1A and a rated power of 0.5W to 12W. The actual output depends on how fast the rotor is spun — either by wind, water flow, or hand-cranking.

Q: Can this generator be used for school science projects?

A: Absolutely! This generator is specifically designed for use in school teaching environments. It is ideal for demonstrating wind power generation, hand-crank electricity, micro-hydraulic systems, and basic AC/DC conversion concepts in physics or STEM classes.

Q: How do I connect the output to an LED?

A: As a three-phase alternator, you simply connect any two of the output wires to the included LED bead. The generator's AC output is sufficient to light the LED when the rotor is spinning at an adequate speed. For DC applications, a small bridge rectifier can be added separately.

Q: Is this generator brushless, and why does that matter?

A: Yes, this is a brushless generator. Brushless designs eliminate the mechanical contact brushes found in traditional motors, resulting in less friction, lower maintenance requirements, and a longer operational lifespan — making it more reliable for repeated classroom use or DIY projects.
