Main Features

 

Step into the future of industrial airflow with the groundbreaking High-Performance 20FT Ceiling Fan, engineered by Fujian Diamond Electrical and Mechanical Equipment Co., Ltd. Our pioneering self-developed external rotor motor is at the heart of this innovation. Featuring an advanced IMU configuration, it powers a seamless ESC active control strategy, harmonized with a sophisticated regenerative braking strategy. This technological marvel combines large torque with permanent magnet synchronization, achieving unparalleled integration that elevates reliability and transmission efficiency to unprecedented levels.

Our state-of-the-art design expertly accommodates any torque recovery or auxiliary braking demands within peak torque, assuring unparalleled performance. We use premium aluminum alloy material across various components, achieving a remarkably lightweight yet robust design, ensuring long-lasting strength and durability.

 

Smart Controller:
1 Enjoy peace of mind with our fully enclosed design, offering an IP66 protection grade. This ensures exceptional dust-proof, waterproof, and moisture-proof capabilities, making it highly resilient to high temperatures and ideal for both indoor and outdoor environments, no matter how challenging.
2 Our system operates without a position vector control, fortified against electromagnetic interference and radiation. It features a compact, lightweight, and visually appealing design, ensuring seamless integration into any setting.

3 Relish in ease of operation with our system's user-friendly interface. Featuring just four intuitive buttons, control is effortless: start, stop, speed up, and slow down.

4 Equipped with comprehensive protection features, our system defends against overvoltage, undervoltage, voltage loss regulation, current anomalies, phase deficiency, overload, collision, overheating, and lightning, safeguarding against all potential abnormalities.

5 Tailor your experience with our intelligent control mode options, thoughtfully designed to cater to your specific needs and preferences.

Fan Blade: Crafted from high-strength aluminum-magnesium alloy used in aviation, our fan blades undergo a meticulous extrusion and stretching process. Internally reinforced, they offer unparalleled strength, superb toughness, and are lightweight, ensuring prolonged service life and safe operation. The T5+ surface bright oxidation treatment further enhances corrosion and oxidation resistance, making it ideally suited for specialized environmental applications.

Tail:
As our fan blades spin, the airflow generates vortices at the
end of the aerofoil blade. Our cutting-edge tail wing design
effectively neutralizes this energy loss, ensuring smooth and
stable operation while optimizing airflow alignment with aerodynamic principles.
