Main Features

 

Discover the innovation of industrial airflow with our state-of-the-art, self-developed external rotor motor. This marvel of engineering is paired with an advanced IMU configuration that facilitates an effortless ESC active control strategy and a synchronized regenerative braking strategy. With its robust design, this technology offers immense torque and permanent magnet synchronization, ensuring a seamless integration that significantly enhances both reliability and transmission efficiency, setting new standards in industrial fan performance.

Our groundbreaking design supports all torque recovery and auxiliary braking requirements within peak torque limits, guaranteeing unparalleled performance. By utilizing premium-grade aluminum alloy materials in various components, we deliver an exceptionally lightweight design that maintains strength and durability, ensuring longevity and resilience.

 

Smart Controller:
1 Experience tranquility with our fully enclosed design, featuring an IP66 protection grade that offers unparalleled dust-proof, waterproof, and moisture-proof capabilities. This makes our product highly heat-resistant and ideal for both indoor and outdoor environments, regardless of conditions.
2 Our system is designed to operate without position vector control, is robust against electromagnetic interference and radiation, and showcases a compact, lightweight, and visually appealing design.

3 Benefit from our system's intuitive, user-friendly interface that requires just four simple buttons for operation: start, stop, speed up, and slow down, ensuring effortless control.

4 Our system includes comprehensive protection features to guard against all potential issues, such as overvoltage, undervoltage, voltage loss regulation, current anomalies, phase deficiency, overload, collision, overheating, and lightning protection.

5 Personalize your experience with our intelligent control modes, expertly crafted to meet your unique needs.

Fan Blade: Our fan blades are expertly crafted from high-strength aluminum-magnesium alloy used in aviation, undergoing a precise extrusion and stretching process. These blades are internally reinforced for superior strength, outstanding toughness, and light weight, ensuring a long-lasting service life and safe operation. The T5+ surface bright oxidation treatment further enhances corrosion and oxidation resistance, making them perfect for challenging environmental applications.

Tail:
As the fan blades rotate, airflow creates vortices at the
aerofoil blade's tip. Our cutting-edge tail wing design effectively
eliminates this energy loss, ensuring a smooth and stable
fan operation while maximizing airflow efficiency to align perfectly with aerodynamic principles.
