Al-Pc Complex Blade

The Original and Initial Technology

Two materials compose the blade.

Shell made by plastic

Skeleton by extruded aluminum

Shell is supported by skeleton.

Reduce weight up to 40%:

• Lightweight, consume less energy.

• No resonance as made up by two different materials.

• Lessen metal fatigue

• With equivalent driven power, achieve better performance.

Extruded Plastic Blade

The Original and Initial Technology

Using extruded process for long blade.

• Lower melt temp，lower energy consumed in manufacturing process.

• Easy clean, no water stain left after water washed.

Blade Interconnect Grille

The Original and Initial Technology

A nylon cord connects all blades in turn to form a close ring.

3-5 such rings along the radial to makeup a protective grille.

Every blade is interconnected by a nylon Cord.

• The accident blade tired by its adjacent blades would floate overhead and easily be Identified and replaced to avoid posibble hurt accident underneath.

Blade Skeleton Interconnect Ring

The Original and Initial Technology

A nylon cord connects all blades one by one through a hole on vertical side of skeleton.

Separation of anti-fall function and bolts fasten.

• The anti-fall function and bolt fasten separated.

• Lightweight of nylon cord add a little load to blades.

PMSM motor series

Model: BRK-LD1.1,/D12,-/D11,   -/ D10

Summary on anti-fall device

From roof beam to motor rack, a steel rope goes through the key components and locks them together, form a security ring.

4 steel ropes connect roof and motor rack in tension, as an anti-fall measure and stabilization function to the rack.
