PMSM Fan
RTFANS use PMSM(Permanent Magnet Synchronous Motor) for low noise, high performance, and efficiency. It is to boot characterized by swish rotation over the full vary of a variable speed motor, total force management at zero speed, and fast acceleration and fastness. To achieve such management, we tend to use field-oriented management FOC techniques (also observed as vector control) for our PMSM.
PMSM used for superior and high-efficiency motor drives. The full speed varies of the motor will characterize excellent management by swish rotation over the whole speed vary of the automobile, total force management at zero rates, and fast acceleration and fastness.
What is PMSM Fan?
- Large industrial & commercial fan driven by the PMSM motor saves the reducer link, has no gear and high speed running bearings, so it absolves to replace the oil, the reduction of the gear and bearing replacement maintenance thus on. It is very done the maintenance-free and greatly improved the service life of the large industrial fan. It brings loads of reliable experience for the user.
- A magnet motor (PMSM) could also be thought-about a bit like a brushless electricity (BLDC) motor. Like BLDC motors, PMSMs ar rotating electrical motors that have magnet rotors and wound stators. They have a three-phase machine layout that’s meant to form arced flux distribution at intervals the air gap, making the rear voltage (BEMF) arced.

HVLS Fans Wind Chill Effect
The gentle breeze brings by RTFANS HVLS fans to our body can accelerate sweat evaporation and make people feeling cool, usually, this sensible temperature created by wind chill effect can be 5-8℃, in addition, the gentle wind from all sides will make people more comfortable compared with a traditional powerful fan.
How to make people feel cooling down 5-8℃ by use high-volume low-speed fans?
The running of a big diameter industrial fan blade accelerates the airflow and increases the evaporative efficiency of the sweat on a human being’s body, and this evaporation process takes away heat in the body, that’s called the wind chill effect.
As for the specific influence created by different wind speeds, please see the above graph, which can show you different temperatures with different wind speeds to make the difference that people feeling.

HVLS Fan Space Ventilation
Usually, the ventilation is restricted in a tall and large space, and the exhaust fan can barely work for the floor or corner of the building where people and equipment located, while HVLS industrial fan can solve these problems completely by sending a well-aligned wind in full space, coordinated with the evaporative air cooler, to improve the air quality and achieve a healthy and comfortable working environment.
PMSM Fans Dehumidification
RTFANS HVLS industrial ceiling fan facilitates the flow of air and dispenses the damp, to improve the comfort level for people in the house.
HVLS fan can accelerate the air mixing of whole space which helps to distribute and absorb the odors, smoke, and humidity very well, thus improving the quality of air and provide a fresh, arid and safe environment.
