Threephase AC generator that can be connected to any two wires to light LED beads. Key benefits Simple twowire LED lighting: connect to any two wires and LED beads illuminate with threephase output. Versatile power sources: suitable for windpower generation and hydraulic hand friction power generation, enabling offgrid or educational demonstrations. Educational and practical: serves as a teaching aid and textbook model for threephase AC power generation in schools. Battery charging capability: mainly suited for charging small batteries; requires converting AC to DC through rectification and filtering for charging. Maintenance option: when the motor noise increases, gear lubricating oil can be added to the motor gears, helping maintain operation. What this product does Function: threephase AC generator that provides a practical platform for generating threephase power from simple mechanical inputs and powering small loads. Compatibility: connects via two wires to light LED beads directly; for charging batteries, DC output requires rectification and filtering. Performance note: designed for use with wind power and handfriction (hydraulic) power sources to create electrical energy for LEDs and small battery charging applications. Teaching value: useful as a classroom model to illustrate and study threephase AC generation and basic electrical conversion concepts. Usage scenarios Offgrid LED lighting: pair with a windpowered or handfriction generator setup to illuminate LEDs without mains power. Small battery charging: generate AC with the device, then rectify and filter to DC to charge small batteries in a compact, educational setup. Classroom demonstration: use as a handson model in science or engineering classes to demonstrate threephase generation and the need for ACtoDC conversion in battery charging systems. Notes For DC charging, implement rectification and filtering to convert the generated AC to usable DC. If noise increases during operation, add gear lubricating oil to the gears to help reduce the sound.
