1、The traditional folding tail concept of small fans is abandoned and the blade stall and electromagnetic braking mode are adopted to improve product safety and reliability.
2、Unique blade wing design system. Enables the fan to have a low wind start and a noise level of less than 40 dB at rated wind speed.
3、The maximum wind energy utilisation factor CpMAX = 0.45 and the blade was analysed for load and fatigue by the finite element analysis software ANSYS.
4、The back seat yaw system uses a simply supported beam structure, with only positive bending moments in the span, and none of the tensioned prestressing produces additional internal forces in the beam, thus enhancing the turbine's ability to resist storm impacts.
5、The insulation level of the generator reaches class H, the sealing is good and the protection level is IP65, the power generation efficiency is 10% higher than the national standard and the starting torque is low.
