Function and operation This product is a threephase AC generator. It can be connected to any two wires to illuminate LED beads, making it suitable for simple demonstrations and handson experiments with threephase power systems. Maintenance and performance When motor noise increases, gear lubricating oil can be added to the motor gears to help maintain smooth operation and extended life. Target audience for students, enthusiasts, and anyone looking to learn about threephase AC power generation and renewable energy sources. Applications and suitability Windpower generation experiments and demonstrations Hydraulic hand friction power generation setups Teaching aid and textbook model for threephase AC power generation in schools Benefits and what makes it stand out Clear, practical demonstration of threephase AC generation Simple twowire LED lighting setup for immediate visual feedback Versatile for classroom use, projects, and experimental development in renewable energy studies Use scenarios 1) Classroom lab: Use the generator to demonstrate threephase generation and lighting LEDs with a twowire connection. 2) Renewableenergy experiments: Attach to a small windpower setup or hydraulic hand friction system to study electricity generation and energy conversion. 3) Project work: Students can build handson projects to explore threephase power concepts and verify performance with LED indicators.
