This threephase AC generator is designed to demonstrate threephase power concepts and renewable energy sources in an educational or experimental setting. For charging small batteries, AC output must be rectified and filtered to DC power. External rectification and filtering are required. Simple twowire connection: it can be connected to any two wires to light up LED beads, making demonstrations straightforward and accessible. Suitable for windpower generation demonstrations as well as hydraulic hand friction power generation, offering practical handson experiences with energy conversion. Ideal as a teaching aid and textbook model for threephase AC power generation in schools or training environments, helping students visualize concepts in real time. Key attributes Function: threephase AC generator that provides threephase output for educational and experimental use; compatible with external rectification to DC for charging small batteries.
