1. The wind wheel:Using three blades,laminar flow airfoil,high lift-drag and excellent performance.The blades use glass fiber reinforced plastic leaf fiber,with a large damping,good dynamic feature,and good toughness.Wind wheel and generator with flexible connections run smoothly without vibration or noise.

2. Generator:The overload strong bearing,long-lasting lubrication without maintenance.The rotor is made of permanent magnet (NdFeB),so it generates electricity when the rotating impeller drives generator rotor rotating.The wind is different from
ordinary electric motor,which is the ultra-low-speed motor,100 --- 400 per minute to switch that is able to meet the design power (depending on model),while such a low speed of the motor is unable to pronounce with ordinary electricity.

 

3. Switch controller:It is connected generators,batteries or network (if necessary),and electric-powered equipment,electrical installations.The system with different voltage sockets is user-friendly;rectifier that is issued by the three-phase AC generator changing into direct current.On grid and off grid style is optional .

4. Inverter:Wind generators are direct current through the battery output can only be used for the direct current electrical use,using AC appliances must be equipped with the DC into AC inverter,inverter can change from electrical power storing of battery to alternating current suitable for the standard of customers,and then provide utilization for electricity equipment.On grid an off grid is optional .

1,Patent genertor,with low starting up torque,high wind energy utilization.
2,Maglev generator is made of permanent magnet,high power and  low loss

Being installed by human design and easy for installtion,maintenance and repair

Double bearings running low vibration,make it survive stronger wind

Blades are made of high quality aluminum alloy plate,which surface using spray or oxidation treatment,better anticorrosion,more beautiful and durable
