Feature: 1. Three Phase Motor: The wind generator also has a three phase permanent magnet synchronous motor with high efficiency compact alternator with high performance NdFeB permanent magnet. 2. Yaw Adjustment System: Our small wind generators have a yaw adjustment system that automatically reads the wind position and adjusts the rotor position to catch the maximum wind energy. 3. Wind Energy Utilization: Small wind generator has high utilization of wind energy, which can make you have a good experience, the longer the blade, the more energy produced, the more power produced. 4. Nylon Fiber Blade: The blade is made of nylon fiber, which is waterproof, corrosion proof and lightweight, and the tail fin is designed according to the aerodynamic principle. 5. Low Speed Start: Our small wind generator is started at low speed, with low running vibration and high efficiency.
