PMSM Motor HVLS Fans Manufacturer for Public And Commercial Site

Vanse HVLS fans is special designed for large space, low speed and high volume, perfectly solved ventilation, cooling, drying and mould proof in large space.

Vansefans independent R&D to manufacture 5blades HVLS super industrial ceiling fans base on international advanced technology conception which fully satisfied the customer's demands. Patent design hub chassis and blades connection ensure the safety. Comply with modern aerodynamics principle high efficiency blade under the same speed generates more air volume and coverage. 

-----Advantages-----

1. Blade shape-streamlined Variable Cross-section

The fan blade gradually narrows from root to tip and thins to tail then widens,like plane wing, more conform to the equal string length theory of aerodynamic.,more even airflow, higher volume,lower air resistance and energy consumption.

2. Blade Material-aviation Aluminum Sheet

Blade material-Adopt 1.5mm thickness aviation high grade density aluminum alloy original plate, with high strength and flexibility, bright and durable.

3. Blade Weight-light

Each blade 7.7KG(17Ibs),total weight for 5pcs 38.5KG(84.9Ibs).Smaller blades ,lighter weight, reducing the motor load and extend service life, low energy consumption

4. Blade Angle-3 Degree Up

Variable section design, the tip is 3 degrees higher than root, improving the air flow from cylindrical to conical, extend the coverage, more than 1900m2(20445ft2)

5. Blade and Petiole-full Mortise and Tenon Connection

The convex petiole and concave buffer device are locked with bolts, each blade is riveted  with buffer device by 16 rivets,forming the blade, buffer device and petiole as a whole, torque and shear less and less.

6. Petiole and Hub-integral Mortise and Tenon Connection

Lock the petiole in the piston on the hub through concave and convex surface.Petiole and  hub form an integral to prevent the blade from upturning, falling and waggling

It can load more than 8T(17632Ibs) tensile  

7. Buffer Device-rubber Mat

The rubber pad between mounting hole of buffer device and shaped inserts to achieve the flexible connection between petiole and chassis.Rubber mat absorb the most of vibration, improve the motor shaft work conditions, extend the life, more quieter

8. Chassis Structure-integrated Hub

Integrated hub，special-shaped mounting hole and fastener locked each other to prevent the blade from waggling，easy installation,free maintenance.

-----Configuration-----

1. Power: PSMS Motor

1).Small size: 1/3 of geared motor, applicable for more places.

2).Low noise: less 40% than geared motor.

3).Fully enclosed, maintenance free.

2. Controller: 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).Failure protection: 25fail-safe protections (over current,over voltage,under voltage phase loss,overload,etc.)

3. Fan Blade *patent: Variable Cross-section Streamlined Blade

1).5 pieces of 1.5mm thick 5052 aero-grade aluminum plate are adopted, which can withstand more than 3 tons of tension and will not crack when impact.

2).Variable cross-section streamlined blade: fan blade gradually narrows from root to tip and thins to the tail then widens,wind resistance is small, air volume is more uniform.

4. Connection *patent: Structural Connection System

1).Petiole and chassis are connected by trapezoidal ladder clamping groove, and the structure is stressed as a whole without the risk of bolt fracture.

2).Petiole and blade adopt flexible shock absorber to release high-frequency vibration and ensure that the bolts are not impacted.

5. Chassis Assembly: Integrated chassis

7075 aero-grade aluminum material is made by CNC lathe machining with precision process, the shape remains totally same,  well appearance to ensure the best mechanical performance of chassis.
