W.Fans is new large HVLS energry-saving industrial fan based on PMSM (Permanent Magnet Synchronous Motor) principle developed by Dawang.With 260N.m torque,the driving force is more stronger and the torque is more stable.Save 30% energy,IE4 high efficiency.The fan diameter from 2.5M to 7.3M,14850m³/min air volume,free maintain for life,no need to change oil and seal. 20-years reliable life,W.Fans series solves the problem of ventilation and cooling in large spaces with better performance,lower energy consumption and longer life.
 

	Dynamical system:PMSM motor  Dawang motors,free maintenance  Small size: 1/3 of traditional gear motor Low noise:less 40% than traditional gear motor Low energy:min 30% saving than traditional gear motor Low temperature: less than 131^0F
	VFD:Vector Converter 1.Start steady: Motor vector algorithm and current suppression to achieve 2.No noise: up to 16KHZ, no noise during speed up, slow down, and running 3.Restart: It can smooth restart when the blades not completely stopped 4.Failure protection: 25 fail-safe protections (over current,over voltage,under voltage phase loss,overload,etc.)
	Blade:Streamlined variable cross-section 1.0.059''thickness No.5052 aviation aluminum alloy plate,not break when impact 2.To aerodynamic equal chord length theory,the blade narrows and thins from root to tip till tail then widen,more uniform 3.17Ibs per blade(24ft),5 blades total 84.9Ibs.more safe
	Wheel Hub(chassis): 7075 aviation aluminum plate after CNC precision machining,perfect appearance and metal streamline to ensure the mechanical performance.After machining, max tolerance is 100μm, to ensure the dynamic balance.
	1.Blade and petiole connection The convex petiole with concave buffer device form the Joint engaged,eliminate the centrifugal force from the blades when the fan is running and the shear force when the fan starts and stops. The transverse screw is the same direction with fan running track to avoiding the shear in order to ensure the blade will not broken,eliminate the possible Safety hazards radically. 2.Petiole and wheel hub The petiole and hub/motor are integrated by the stepped concave-convex sections to engage each other.The overall structure is used to withstand the centrifugal force during running,and all fasteners are not stressed. 3.Motor and flange roulette Safety ring:Connect the 5 petioles and motor upper cover form the whole,adopt the occlusion structural to even the force of the whole fan. Anti-falling roulette:The concave flange roulette engaged with the convex anti-falling ring each other under the gravity to ensure the reliable connection between the flange roulette and motor.

 

	Dawangfan crash test result: (impacted by forklift )   The blades are still twisted and deformed, does not break or fall.
	Others:   Common profiles,Rigid connection,fan falling cases
