Application of non - inductive brushless DC motor system on industrial ceiling fan

The use of industrial ceiling fans
1. Body cools down

The natural breeze generated by the large energy-saving fan blows on the human body, promoting the evaporation of sweat to carry away the heat, which cools the human body and brings a cool feeling.

In general, this cooling sensation can be as high as 5-8℃.

Huizhu ventilation large industrial fan blowing three-dimensional natural breeze more comfortable human body is because: on the one hand, to the human body in an all-round three-dimensional blowing, so that the evaporation area of the human body to reach the maximum.

On the other hand, human beings accumulate intimate experience of natural wind in the nature. Once there is a natural breeze with the change of wind speed, human body will feel extremely comfortable and cool.

2. Air circulation

In the previous ventilation scheme, people often decide which kind of product and quantity to use according to the ventilation frequency of the space.

This is in small space, the effect is very apparent, you can see with one's own eyes even the steam of the bathroom with the operation of abdominal pressure fan quickly platoon comes outdoors.

However, in the high and wide enclosed space, the ventilation effect is not obvious: for example, the heavy smoke, humidity, carbon dioxide and poor quality air are still concentrated at the bottom of the building, and the negative pressure fan on the roof has no effect on the air in various corners, where the personnel and equipment are.

Huizhu ventilation large industrial fan will promote the air mixing throughout the space, which can make the flue gas with unpleasant smell, moisture, mold, etc. get well dispersed, thus improving the indoor air quality, and achieving a healthy, dry and safe working environment.

3. Environmental dehumidification

If the ventilation and cooling conditions in the building are poor, the quality of products may be reduced, and even a lot of losses and waste may be caused!

In addition, once some materials are deformed by moisture, they will become the first object of customer complaint.

Preventing air condensation, reducing bacteria and mildew, super large industrial fan significantly enhances air flow and controls air condensation on the ground or metal surface, making your working environment cleaner, drier, comfortable and safe.

Drive away stray birds into the room and ensure the internal hygiene of tall buildings.

4. Eliminate hot and cold layering

According to the logistics principle, we know that in a closed space, the temperature rises 1-2℃ for every meter of height, which means it is very difficult to warm the ground in a tall space.

The heat is concentrated on the top of the building while the ground is not as hot as hoped. Industrial fans can easily help you solve this problem: just running at a low speed, the huge blades of large industrial ceiling fans can drive a large amount of air and send heat slowly to the ground, thus eliminating stratification.

Ii. Introduction of non-inductive brushless motor system

With the development of science and technology, people's requirement for DC motor has been constantly improved, which can not meet the disadvantages of traditional brushless DC motor in industrial application.

Sensorless BRUShless DC motor uses indirect measurement of rotor position instead of sensor detection, which can effectively solve many problems brought by sensors to the system.

Advantages of sensorless brushless motor System in industrial production:

(1) Remove the motor internal easily damaged Hall sensor;

(2) Reduce the number of leads of the motor and control system;

(3) Greatly improve the reliability of motor and control system;

(4) Reduce the motor production cost, simplify the production process, shorten the motor development cycle;

(5) Improve the working efficiency of the motor;

(6) Improve the quality of the whole machine.

Iii. Intelligent, non-inductive, brushless Motor System Features:

(1) High performance DSP processor, combined with no position sensor detection technology, speed closed loop, current closed space vector control technology, S-ADRC algorithm, so that it has a wide speed range (general speed ratio can reach 100), small speed fluctuation (0.1%), low speed overload start without jitter, high efficiency and energy saving advantages.

(2) in order to meet the motor running quality of the occasion of high requirements, launched a high-performance series of drivers.

Power range: 0.05~5kW, speed: 30~30000rpm.

Motor parameters automatic identification, so that the driver can adapt to different motors, including three-phase permanent magnet synchronous motor, three-phase stepping motor and three-phase induction induction motor.

Long - line drive compensation function, can meet the motor to drive more than 30 meters between the application requirements, overcome the hall brushless drive in the long - line application of high failure rate.
