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 1310F | |
| 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. |
| A.BLADE DESIGN-Streamline Variable Cross-section The blade section is from wide to narrow (304-186mm),from thick to thin (43mm-21mm).Adopts the equal chord length principle and relative linear velocity characteristics to ensure the balance pressure of the whole blade to achieve the tip,middle and roots air evenly including the middle. B.BLADE MATERIAL-Aviation Aluminum Alloy 1.5mm thickness No.5052H32 aviation aluminum alloy original plate,precision CNC molding,high strength and flexibility ensure the blade not to be broken. C.BLADE WEIGHT-More Lighter and Safer 6.7kg per blade(24ft),less blades,lighter weight,it can reduces the motor load,prolong the life,more safer and cost-efficient | |
| A.EPDM BUFFER RUBBER EPDM high-strength rubber in the buffer cavity,it absorbs the blade stress and airflow vibration,reducing the motor load,extend the motor life and more quieter. B.UPWARD 0-1.5 DEGREE The buffer cavity with the groove adjusts freely to upward 0-1.5 degree when the fan runs under the airflow,eliminate the reverse force generated during the operation,reducing the rebound and pressure then forms a conical airflow to cover more areas. | |
| A.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. B.PETIOLE and WHEEL HUB The concave-convex section integrates the petiole and hub/motor,the whole fan withstand the centrifugal force and all fasteners are not stressed. C.MOTOR and FLANGE ROULETTE Anti-falling ring(Geared motor Fan):Connect the 5 petioles into a whole to form the sleeve with frame lower hub to prevent the hub from falling. Anti-falling roulette(PMSM fan):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. |
