Permanent Magnet Variable-Frequency Mobile Large Fan

The HuaDa HDY series permanent‑magnet variable‑frequency mobile large fan is a product specifically developed to enhance environmental comfort. It features a self‑designed, variable‑frequency, high‑efficiency, energy‑saving permanent‑magnet external‑rotor synchronous motor. It boasts advantages such as low noise, compact size, light weight, a streamlined design, an attractive appearance, and easy portability.

Widely used in high‑ceiling spaces such as fitness centers, outdoor weddings, industrial plants, logistics warehouses, waiting areas, exhibition halls, sports arenas, and large shopping malls and supermarkets, this innovative portable fan provides spatial ventilation and helps cool people. It can deliver a powerful airflow, creating dynamic air movement within a defined area to promote overall air circulation—mimicking nature’s gentle breeze for a refreshingly natural experience.

The HDY series of permanent‑magnet, variable‑frequency large fans features a unique airfoil‑shaped blade design with diameters ranging from 1 to 2 meters. Crafted using aerodynamic principles and advanced manufacturing techniques, these airfoil blades generate a circulating airflow through powerful air‑mixing action, creating a gentle breeze that closely mimics nature. This delivers multidirectional, three‑dimensional airflow, increasing the surface area for sweat evaporation and enhancing comfort. At the same time, it avoids the health issues often associated with traditional high‑speed fans operating continuously in a directed airstream, significantly improving environmental comfort. The HDY series fans can be adjusted to suit the specific needs of different settings, with wind speed controllable between 1 m/s and 7 m/s. In open spaces, a single energy‑efficient fan can deliver air up to 28 meters away.

Permanent Magnet Synchronous Motor

Features:

• The rotor has no copper losses.
• High efficiency, high precision
• High power factor

Airfoil-shaped fan blades   
It is manufactured using aluminum–magnesium alloy through extrusion and stretching, featuring an airfoil‑shaped internal rib structure. This design offers high strength, excellent toughness, light weight, long service life, and safe operation. The fan blade surface undergoes T5+ bright‑finish anodizing, which enhances its corrosion and oxidation resistance, enabling it to withstand extreme… 
Work in special environments.

Energy-saving tail fin   
Made from high-temperature‑resistant materials, the product boasts a more aesthetically pleasing design. As the fan blades rotate, vortices form at their trailing edges; the tail fin helps dissipate this energy loss, stabilizing the fan’s operation and ensuring airflow aligns more closely with aerodynamic principles.

Adjustable air supply angle (custom model) 
In various settings, the airflow direction of a fan needs to be more flexible and adaptable; this is where the adjustable-angle Model B portable fan truly shines. The tilt angle can be adjusted from –45° to +45° (with horizontal airflow at 0°), in 15° increments, for a total of seven settings.
