Cause permanent magnet fans are not well known, so let's learn about a permanent magnet motor.
Please visit our website for more information on this topic.
Electrical Machine is essentially an energy conversion device (Electrical energy and mechanical energy can be exchanged), including electric motors and generators. Of course, industrial fans use the most commonly used electric motors.
The fan blades can be turned on by making a simple electric motor consisting of a battery, a screw, a wire, a magnet, and fan blades.
What is the relationship between the magnet and permanent magnet motor? A permanent magnet motor is made of magnets, but the name magnet is not high enough; the technical term is generally called "permanent magnet."In this simple motor, we use an electromagnet, also known as a magnet, which is a naturally magnetized stone in nature that can magically pick up small pieces of iron and always point in the same direction after swinging at will.
The great physical scientist Andre-Marie Ampere (-) is no stranger to Ampere's law, which provides an in-depth summary of how electricity generates magnetism.
Then Faraday's law of electromagnetic induction, the representative of experimental physicists, revealed the mystery of how magnetism produces electricity.
So what is a permanent magnet synchronous motor?
Ampere's law tells us that electric currents generate magnetic fields, and we want magnetic fields to interact with each other, so as long as there's a current, it's a natural idea to think about: can a coil generate one of the two magnetic fields? Of course, that's what permanent magnet synchronous motors do.
After continuous development and maturity, the windings of a classic permanent magnet synchronous motor are as follows:
The 3-phase winding is arranged at an electrical Angle of 120° in space, and the three-phase alternating current with a phase difference of 120° is transmitted in the winding.
What are the advantages and disadvantages of a permanent magnet synchronous motor?
Expensive rare earth elements are used to manufacture permanent magnet motors, so motor costs must be relatively high.
Because the permanent magnet material is afraid of high temperature, the motor has the risk of demagnetization in the case of high temperature, vibration, and overcurrent.
The high-temperature resistance grade of a permanent magnet motor can be divided into:
N series, 80 °; H series, 120 °; SH series, over 150 &#;.In addition, abnormal heat dissipation device of the motor leads to high temperature of the motor, Excessive ambient temperature; the motor without equipping with temperature protection device; Unreasonable motor design and other factors can lead to demagnetization of the motor.
To solve these problems, Jiangsu GAXIAO allied with Tsinghua university and Zhejiang university to deal with these problems and develop the PMSM permanent magnet synchronous motor - "Battleax" series.
GX HVLS FAN permanent magnet fan high-temperature class: SH series, more than 150 &#;.

In addition to the fully enclosed structure on the side part of the motor, the hollow structure on the upper part and the lower part provides an excellent heat dissipation effect:
Jiangsu GAXIAO research and develop the permanent magnet motor application of good motor design, temperature management, testing, and manufacturing technology. So that the motor is high efficiency, energy-saving, high speed, precision, reliability, and other aspects of the unique advantages, the GX fan is a real high-quality industrial fan.
So, what is the actual operation effect of the GX HVLS industrial large fan permanent magnet "Battleax" series? Please refer to the following parameter table:
Like 7.3 meters diameter fans, work covers the area of square meters; what is this concept: as in the 40 meters from the center of a fan you still can feel the cool wind blast, this is Jiangsu GAXIAO big fan industrial power and charm of the large scope for you to send cool and refreshing, truly realizing large ventilation cooling.

7/31/When it comes to large area ventilation and cooling, industrial fans must be the best choice.It has been more than ten years since MACROAIR produced and launched the world's first industrial fan in . Over these years, electric motors have been made huge breakthrough, from using traditional speed reduction motors, to the more advanced and portable BLDC brushless dc motors, finally producing the more efficient, more energy-saving, ultra-silent permanent magnet synchronous motors.Gaxiaofan Press Department7/31/
HVLS fans are commonly used in both industrial and commercial settings for ventilation and cooling. While traditional HVLS fans come equipped with gear systems, the more modern PMSM HVLS fans have become a popular option due to their compact design and superior performance.
PMSMs, also known as Permanent Magnet Synchronous Motors, have a number of key advantages that make them a preferred choice for HVLS fans.
One of the most notable benefits of PMSM motors is their high power output, efficiency, and power factor. PMSM motors generate less heat compared to traditional HVLS fans, and as a result, they have a more straightforward cooling system that is smaller in size, quieter, and requires less maintenance.
The PMSM design features a fully enclosed structure that eliminates the need for transmission gears, which in turn eliminates noise, the need for lubrication, and the need for maintenance. This feature also makes the system lighter in weight and reduces the unsprung weight, making it more efficient and powerful per unit weight.
Another advantage of PMSM motors is their ability to withstand large overload currents, which significantly improves the reliability of the system. Additionally, the absence of a gearbox in the PMSM design allows for greater flexibility in designing the bogie system. This, in turn, results in improved dynamic performance.
Finally, the PMSM motor can be directly mounted on the axle to form an integral direct drive system, eliminating the need for a gearbox. This design feature simplifies the overall structure of the HVLS fan and enhances its performance.
In conclusion, PMSM HVLS fans offer a number of benefits over traditional HVLS fans with gear systems. With their high power output, efficiency, and reliability, PMSM HVLS fans are an excellent choice for industrial and commercial applications that require effective ventilation and cooling solutions.
