The permanent magnet synchronous industrial fan adopts a newly designed lightweight and efficient permanent magnet synchronous motor, with an 18kg body capable of outputting a super large air volume of 10000m3/min. The digital modeling of the entire machine and the production of component molds have effectively improved the reliability and safety of the product. The special cross-sectional design reduces the weight of the fan blades while ensuring their strength and sufficient air output efficiency. It can generate circulation in the space, promote air circulation, and provide personnel with a cool and comfortable environment like bathing in forest wind.
