Workshop large industrial fan is a common industrial machine used for space ventilation and personnel cooling. It is commonly used in industrial plants, logistics warehouses, waiting room, exhibition halls, stadiums, supermarkets and other large spaces. The industrial fan can push a large amount of air flow to the ground, forming a certain height of horizontal movement of the air flow layer on the ground, thus contributing to the overall air circulation. This benefit lies in the all-round ground coverage and three-dimensional air circulation. From this, it can be seen that the industrial large fan in the workshop not only plays a role in cooling the space, but also serves as a machine for ventilation and ventilation in the workshop.

Configuration

At present, the configuration of permanent magnet motors in the industrial fan market is mainly divided into two categories: external rotor permanent magnet motors and internal rotor permanent magnet motors. The neodymium iron magnetic material of the outer rotor motor is adhesive type. In case the adhesive ages and fails, causing the neodymium iron magnetic material to fall off, it will cause the stator and rotor of the motor to get stuck. Once it gets stuck, the motor will be immediately scrapped and users will suffer great losses.

The neodymium iron magnet material of the inner rotor motor is embedded and fixed by the structure, without the phenomenon of adhesive aging and failure. There is no risk of neodymium iron magnet material falling off, so the warranty period of the inner rotor motor on the market is longer than that of the outer rotor motor.

Selection of Core Materials for Permanent Magnet Motors

The grade of core materials determines the different heat resistance coefficients of permanent magnet motors. Under the same operating environment, the temperature rise is the same, and the difference in material heat resistance coefficients affects the stability of equipment quality. The higher the material grade, the higher the heat resistance performance, and the corresponding increase in production costs.

Four major functions of permanent magnet fans

Cooling

Industrial large fans can effectively solve the problem of personnel cooling in industrial factory buildings. Industrial factory production can have a certain degree of stuffiness, especially in specific spring and summer when there is severe heat sensation. The natural breeze generated by industrial large fans blows on the human body, promoting the evaporation of sweat to take away heat, cooling the human body and bringing a cool feeling. It is one of the most effective cooling methods. Usually, this cooling sensation can reach 5-8 ℃. Bringing a comfortable experience of natural wind to the human body.

Environmental dehumidification

If the ventilation and cooling conditions inside the building are poor, it may lead to a decrease in product quality and even cause significant losses and waste. In addition, some materials will become the subject of customer complaints once they become damp or deformed. To prevent air condensation, reduce bacteria and mold, the oversized industrial fan significantly enhances air flow and controls air condensation on the ground or metal surfaces, making the working environment cleaner, drier, more comfortable, and safer.

Ventilation and impurity removal

In various production workshops, especially manufacturing workshops, metal dust, wood dust, and zero harmful smoke are generated to some extent during the production process. Although the factory building is tall and spacious, it is relatively independent in space. When the air circulation is poor, the concentration of dust or harmful gases is too high, which affects the health of workers and even causes occupational diseases. By using a permanent magnet industrial large ceiling fan to rotate and remove air flow throughout the entire workshop, it has a significant effect on improving air quality.

Equilibrium temperature

In winter indoors, the hot air generated by air conditioning accumulates on the top floor, while the ground temperature is moderate and low. Low speed industrial energy-saving fans can slowly send hot air from the roof to the ground, which can balance indoor temperature and avoid energy consumption caused by uneven temperature.

The permanent magnet industrial fan adopts a permanent magnet brushless servo motor, which is directly driven by the servo and has no brush or sound; Maintenance free, no oil pollution, sealed structure design, protection level IP64, truly achieving maintenance free and maintenance-free motor.

Advantages of permanent magnet fans

Reduce weight and volume

Traditional industrial fans cannot achieve low-speed operation function with motors, so they must be used in conjunction with reducers. However, permanent magnet direct brush industrial fans only require one permanent magnet motor, reducing the reducer and reducing the volume and weight of the entire fan by 60%.

Complementary cooling systems

Perfect combination with air conditioning, evaporative air conditioners, and negative pressure fans, inheriting innovative ventilation and cooling systems;

Reduce maintenance

Because the gearbox of traditional industrial fans requires regular lubrication, while industrial fans are usually installed in a large space of more than 5 meters, maintenance is particularly inconvenient, and permanent magnet motors can perfectly solve this problem, almost achieving true maintenance free.

Wide coverage area

Utilizing the rotation of large diameter fan blades to push a large amount of air to the ground, forming a certain height of airflow layer on the ground that moves horizontally along the surroundings, promoting the air circulation of the entire space; Its low speed, low energy consumption, high air volume, and wide coverage area.

Security

The installation of permanent magnet fans does not require complex circuit measures, and is relatively safe to use. It can ensure the physical and mental health of employees and reduce safety issues caused by unscientific electricity use. The high-volume industrial ceiling fan generates a low-carbon and low-cost indoor ventilation circulation system based on the combination of power and operating system. It can be used to achieve natural ventilation and cooling in large-scale indoor environments, allowing employees to enjoy cool air even in hot and hot summers, completely solving the problem of natural ventilation in super large spaces, and creating a comfortable working environment, including maintaining environmental hygiene and safety.
