Ideal for students, enthusiasts, and anyone who wants to learn about threephase AC power generation and renewableenergy sources through handson practice. Versatile for windpower generation and hydraulic hand friction power generation, and suitable as a teaching aid or textbook model for threephase AC power generation in schools. This is a threephase AC generator that can be connected to any two wires to light up LED indicators, providing a simple, visual demonstration of threephase output. If motor noise increases, you can add gear lubricating oil to the motor gears to reduce noise and help maintain performance. Use scenarios Classroom demonstrations: show threephase generation concepts and energy conversion using wind or handcrank input, with LEDs as visible indicators. Smallscale renewableenergy learning projects: connect wind or hydraulic handfriction input to illuminate LEDs and study output characteristics. Educational demonstrations or textbook applications: use as a practical model to illustrate threephase AC generation in physics or engineering curricula.
