PMSM is a permanent magnet synchronous motor. What is called a permanent magnet, refers to adding permanent magnets when manufacturing the rotor of the motor in order to improve the performance of the motor. The synchronous means that the rotation speed of the rotor is always consistent with the electric current frequency of the stator winding.
Permanent magnet motors have a higher power-to-weight ratio, smaller size, lighter weight, and larger output torque than other types of motors, and the motor’s limit speed and braking performance are also excellent, so it is the most used motor in electric products at present.
Typical applications for HVLS fans fall into two classifications—industrial and commercial. HVLS Fan can be installed in any big space which is higher than 4m.
The breeze brought by the HVLS fans blows toward the human body from a tridimensional direction, accelerating the evaporation of sweat, and making people feel cool. Usually, the temperature caused by the wind chill effect can reach 5-7°C. In addition, compared with traditional powerful fans, the breeze from all directions will make people more comfortable.
Ventilation is usually restricted in a tall and big spaces, and the exhaust fans can hardly work for the floors or corners of buildings where personnel and equipment are located. While HVLS fans can completely solve the problem by sending out a well-aligned wind in full space, cooperating with roof ventilators, improving air quality, and realize a healthy and comfortable working environment.
