PMSM Big Ceiling Fan Industrial Ventilation For Public And Commercial Site
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.
Confirguation
MOTOR SYSTEM:PMSM MOTOR
1.More stronger:260N.m torque,more stronger,more stabler torque,air volume increases 30%.
2.More efficient:Unique outer rotor high torque design,higher accuracy.
3.More energy saving:30% energy saving,up to IE4 high-efficiency energy-saving standards,GB30253-2013 national energy efficiency new standard.
4.Free maintenance for life :Totally sealed,no need to replace lubricating oil,seals and other accessories,more cost-effective.
5.Lower noise:38db lower noise,more comfortable.
6.Lower temperature:Motor raised temperature lower than 35ºC,longer life
VFD:VECTOR CONVERTER
1.More steady:New generation of high-reliability IGBT modules,Motor vector algorithm and
current suppression let the start more steady.
2.More quiet:Up to 16KHZ,no noise during the speed up, slow down and running.
3.More reliable:PCBA three-proof paint treatment,durable and long life.
4.Restart: It can smooth restart when the blades not completely stopped.
5.Failure protection:More than 25 fail-safe protections (over current and voltage,under voltage,phase loss,overload,etc.)
CONNECTION:PATENTED FULL MORTISE AND TENON STRUCTURAL DESIGN TO ENSURE THE WHOLE FAN SAFETY:
1.BLADE and PETIOLE Mortise and tenon 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.
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
