Permanent Magnet Frequency Conversion Large Ceiling Fan

Permanent Magnet Frequency Conversion Large Ceiling Fan Overview

1. Higher Efficiency

VEICHI industrial fan adopts PMSM (Permanent Magnet Synchronous Motor) technology with a unique external rotor high-torque design. Tested by STIE, motor efficiency reaches up to 84%. Certified under GB30253-2013 national energy efficiency standard – Grade 1 energy efficiency.

2. Quieter Operation

Traditional motors typically generate noise levels above 50dB. The PMSM technology significantly reduces operational noise – VEICHI fans achieve as low as 38.7dB, creating a quieter and more comfortable working environment.

3. More Compact Design

Direct-drive PMSM system eliminates bulky gearboxes and reduces overall unit size. Traditional asynchronous motors require 1.2M installation height; VEICHI fan main unit is only 0.21M high, requiring just 0.80M clearance – ideal for spaces with overhead obstructions such as cranes or piping.

4. Maintenance-Free

Conventional fans require regular lubrication and gearbox oil changes every 20,000 hours – costly and dangerous due to elevated work. VEICHI PMSM fan features sealed double-bearing transmission with magnetic induction drive – truly maintenance-free – saving time, labor, and ongoing costs.

5. Energy Saving

Direct-drive PMSM system eliminates energy loss from gearbox friction found in traditional asynchronous motor systems, significantly improving overall drive efficiency and reducing power consumption.

6. Cost-Effective

No gearbox oil replacement, no routine maintenance, lower noise, and higher efficiency – VEICHI PMSM industrial fan delivers long-term savings on labor, parts, and energy, while ensuring reliable performance in demanding environments.

Large Industrial Fan Safety Measures

The super-large size of VEICHI Brand Industrial fans gives you doubts about safety. In fact, it is not necessary. The company team has studied this very carefully. The measures taken have been proved theoretically and tested strictly in practice, and won many national patents. And get high-tech enterprises in Suzhou.

Installation Requirements and Ceiling Fan Specifications

1. When accidents occur, the safety ring plays a protective role to prevent any parts from sliding; when the bottom fixture is loosened, the fan will fall in the vertical plane. The insurance hook can catch the shelf. Make sure that the lower part of the fan does not fall off.

2. Re-connect all fan-blades and chassis to form a whole structure. The upper and lower layers of the fan blades are fixed to ensure that the blades and chassis become a whole. The bolts used are self-locking bolts to eliminate the danger of loosening.

3. All fasteners are up to 10.8 grade of the highest strength industrial bolts, the actual stress is more than 10 times.

4. The stress intensity of each wire cable can reach 1000KG, and double protection is set at each connecting point; it can bear the weight of the fan at rest; when the fan is inaccident, the fan can be suspended in the air to avoid falling danger. The blade is connected by the second safety hook to prevent accidental falling off. When the danger occurs, the damage to the main fixed beam is reduced to the lowest level. In the process of fan rotation, due to the action of reaction force, the fan almost floats in the air, and the weight of each component is very small.

5. can achieve the firm hand can not reach; in the installation process, all fixtures are used electric wrench, to ensure the quality of the project.

6. When the fan is abnormal, the frequency converter will automatically alarm and stop running.

Application Cases

The adaptability is stronger. The height of the product itself is only 65 centimeters, which can be used in more places. Many factories which used to have smaller space on the top of the vehicle can now be installed without restriction.
