Threephase AC generator for small scale power generation and educational use. It provides threephase AC output and can be connected to two wires to light LEDs. For charging small batteries, AC must be rectified and filtered to DC. It is suitable for wind power generation and hydraulic hand friction power generation, and can be used as a teaching aid and textbook model for threephase AC power generation in schools. When the motor noise increases, gear lubricating oil can be added to the motor gears. Key benefits Versatile power source for small projects: use with wind power generation or hydraulic hand friction generation, and as a teaching aid for threephase AC power generation in schools. Simple LED demonstration: this threephase AC generator can be connected to any two wires to light LED beads, enabling an easy visualization of threephase output. Battery charging option: mainly suitable for charging small batteries; to use with DC charging, AC must be rectified and filtered to DC. Maintenance guidance: if motor noise increases, add gear lubricating oil to the motor gears to maintain smooth operation. Educational and practical value: ideal as a classroom demonstration, textbook model, and handson example of threephase generation in realworld setups. Use scenarios Offgrid wind experiments: connect a small wind turbine to drive the generator, illuminate LEDs, and route the output through a rectifier to charge small batteries. Manual hydraulic power demonstrations: use hydraulic hand friction to drive the generator, showing threephase generation concepts in a practical handoperated setup. Classroom teaching and lab work: employ the generator as a teaching aid or textbook model to illustrate threephase AC generation, wiring, and LED illumination with a twowire connection.
