Frequently Asked Questions

Q: What output voltage does this mini brushless generator produce?

A: The generator produces an AC output voltage ranging from 3V to 24V depending on the rotational speed applied — whether by hand crank, wind turbine blades, or a micro-hydro water wheel. The output current ranges from 0.1A to 1A with a rated power of 0.5W to 12W.

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

A: Absolutely! This three-phase AC brushless generator is specifically well-suited for school and university teaching demonstrations. It's compatible with micro-wind, micro-hydro, and hand-crank friction power setups, and even comes with an LED so you can immediately demonstrate electricity generation.

Q: How do I connect the three-phase output wires?

A: The three-phase output can be connected in multiple configurations depending on your circuit needs. For a simple LED demonstration, just two of the output wires are sufficient to light up the included LED. For rectified DC output, you can use a bridge rectifier circuit with the three-phase leads.

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

A: Yes, this is a brushless alternator. Brushless generators have fewer moving parts in contact, which means lower friction, longer operational life, and less maintenance compared to brushed motors — making them ideal for repeated experimental use or long-term DIY projects.
