Function and output: This is a threephase AC generator. It can be connected to any two wires to light LED indicators, making it easy to observe threephase operation with minimal wiring. Electrical compatibility and charging: Primarily suitable for charging small batteries. When using this motor/generator to charge batteries, AC output must be converted to DC, which requires rectification and filtering to obtain a usable DC supply. Applications and versatility: Suitable for windpower generation and hydraulic hand friction power generation. It also serves as a teaching aid and textbook model for threephase ACpower generation in educational settings. Maintenance: If motor noise increases, apply gear lubricating oil to the motor gears to maintain smooth operation. Use scenarios: Educational demonstration: In a classroom or lab, connect the generator to LEDs with two wires to visualize threephase generation and learn how threephase output behaves. Smallscale energy projects: Use with windpower or hydraulic handcrank setups to generate AC, then rectify and filter as needed for demonstrations or experiments in energy conversion. Battery charging experiments: Use as a source of AC power for charging small batteries after rectification and filtration, enabling practical exploration of AC to DC conversion in a teaching or hobby project.
