The exmork wind turbine products adopt high magnetic neodymium iron boron material (NdFeB), the professional magnetic circuit design, increase the magnetic fields, thereby enhance the generating efficiency. Meanwhile, the weight of the generator is reduced and is the half weight of the like products of other manufacturers. Accordingly, this is easier to install and maintenance.

The exmork wind turbine blades use the import FRP(Glass fiber reinforced plastic),the solid petioles equipped with steel bushing, put an end to the blades broken by the wind pressure and flick out. The surface has the coating, can prevent freezing and aging. The wings shape is good and had tested the wind tunnel test in Sichuan province, running smoothly and quietly, the efficiency value Cp can reach to 0.42.

The special tail vane is in advance partial angle design, when under the normal operation can automatic alignment windward direction, enhance the output power and at the same time can take account to both cornering adjust the speed and the strong breeze protection. When the wind speed is more than 16m/s, the blades windward side will folder to 90°with the tail vane. This will make the blades lost the motive power and give the purely mechanical automatic braking function.
