DIY Spiral Breeze Wind Turbine Model Permanent Magnet Generator Vertical Axis : 1.Low starting wind speed, small running vibration, fast speed and high brightness 2. Use humanized mainstay design, solid and stable 3. The wind rotor blades are made of PAL material, with optimized aerodynamic shape design. Meter and mechanism design, low starting wind speed 4.The generator adopts permanent magnet DC power generation, which has a simple structure. The characteristics of reliable operation, but also reduce the loss of the engine, the efficiency, high speed. 5.The blade is made of PAL material, which is not easy to be corroded, and is solid and firm. 6.The main pillar is surrounded by 4 small LED bulbs. The faster the blade rotates, the brighter the bulb is, the longer the life is, and the less energy is consumed. 7.Not only is it a model, but it can Installation on the balcony or outdoors is also a scenic line. It can be used for interior decoration, scientific experiments, model making, teaching lectures, office furniture, field emergency, etc. Product Specifications: *name: Spiral wind turbine model *Material: PAL *color: White *Product size: 7mm100mm210mm *Aperture: 4mm *Hole distance: 58mm package includes: 1Spiral wind turbine model
