Primary function and power flow: Mainly suitable for charging small batteries. When used as a generator, AC power must be converted to DC power through rectification and filtering before charging. Generator type and simple wiring: This is a threephase AC generator that can be connected to any two wires to light up LED indicators. Applications and suitability: Suitable for windpower generation and hydraulic hand friction power generation. It can also be used as a teaching aid and textbook model for threephase AC power generation in schools. Target users: for students, enthusiasts, and anyone looking to learn about threephase AC power generation and renewable energy sources. Use scenarios: 1) Wind turbine setup: Attach the generator to a small wind turbine, rectify and filter the output to DC, and charge a small battery. 2) Handcrank or hydraulic friction setup: Drive the generator by hand or hydraulic friction to power LEDs, demonstrating energy conversion. 3) Classroom demonstration: Use as a handson model to teach threephase AC power generation and its practical applications in renewable energy.
