Main Features

 

Experience the future of industrial airflow with our revolutionary self-developed external rotor motor. Equipped with an advanced IMU configuration, it enables a seamless ESC active control strategy paired with a coordinated regenerative braking strategy. This powerhouse of technology boasts a large torque and permanent magnet synchronization, offering a high degree of integration that elevates both reliability and transmission efficiency to new heights.

Our cutting-edge design accommodates any torque recovery or auxiliary braking needs within the peak torque, ensuring unmatched performance. We incorporate premium aluminum alloy material in multiple components, achieving an impressive lightweight design without compromising on strength or durability.

 

Smart Controller:
1 Experience peace of mind with our fully enclosed design, boasting an IP66 protection grade. This ensures superior dust-proof, waterproof, and moisture-proof capabilities, making it highly resistant to high temperatures and perfect for indoor and outdoor environments, no matter how harsh.
2 Our system operates with no position vector control, is fortified against electromagnetic interference and radiation, and features a compact, lightweight, and aesthetically pleasing design.

3 Enjoy effortless operation with our system's user-friendly interface, featuring just four buttons for easy control: start, stop, speed up, and slow down.

4 Our system is equipped with comprehensive protection features, including overvoltage, undervoltage, voltage loss regulation, current anomalies, phase deficiency, overload, collision, overheating, and lightning protection, safeguarding against all abnormalities.

5 Customize your experience with our intelligent control mode options, tailored to meet your specific needs.

Fan Blade: Crafted from high-strength aluminum-magnesium alloy used in aviation, our fan blades undergo a precise extrusion and stretching process. Internally stiffened, they offer exceptional strength, excellent toughness, and are lightweight, ensuring a long service life and safe operation. The T5+ surface bright oxidation treatment enhances corrosion and oxidation resistance, making it ideal for specialized environmental operations.

Tail:
As the fan blades spin, airflow generates vortices at the
aerofoil blade's end. Our innovative tail wing design effectively
eliminates this energy loss, ensuring smooth and stable fan
operation while optimizing airflow to perfectly align with aerodynamic principles.
