What is the FG (Frequency Generator) of cooling fan
The FG (Frequency Generator) function of Cooling Fan, commonly referred to as Tach Out , primarily serves the purpose of outputting a square wave signal from within the fan. The frequency of this signal is indicative of the fan's operational speed. For conventional four-pole fans, speed can be calculated as FG frequency multiplied by 30; thus, monitoring the FG signal allows for accurate determination of the fan's rotational speed.
Automatic assembly line commissioning completed
After several months of hard work, our state-of-the-art automatic assembly line has been successfully installed and thoroughly debugged. This cutting-edge production line represents a significant leap forward in our manufacturing capabilities, capable of cooling fan producing an impressive 10,000 fans per day. This not only increases our production, but also saves a lot of labor, equivalent to the workload of five to six employees.
What is a brushless cooling fan motor
What is a brushless cooling fan motor?
The brushless DC cooling fan motor is composed of a motor body and a driver, and is a typical mechatronic product. Brushless motor refers to the motor without brush and commutator (or collector ring), also known as the commutatorless motor. As early as when the motor was born in the last century, the practical motor produced was a brushless form, that is, an AC squirrel cage asynchronous motor, which was widely used. However, asynchronous motors have many insurmountable defects, so that the development of motor technology is slow. Transistors were born in the middle of this century, so a brushless DC cooling fan motor that uses transistor commutation circuits instead of brushes and commutators came into being.
Understanding the principle and installation of DC cooling fans
DC cooling fan is an important cooling device in modern industry, which is widely used because of its simple structure, easy installation, good heat dissipation effect and long service life. So what is the structure and principle of DC cooling fan, and how to buy and install it reasonably?
P-Q curve: More significant than parameters,
The air volume and static pressure of the fan are not fixed but vary with changes in system impedance. The actual air volume and static pressure are determined by the impedance. By obtaining different air volumes under varying...
Inverse relationship between air volume and wind pressure
The concept of air volume is relatively easy to understand, refers to the volume flow per unit time, the simplest way to calculate is Q=vA, v is the fluid speed, A is the area of flow. The unit of air volume in the cooling fan is usually...
Really understand the air volume and pressure of the cooling fan
On the introduction of cooling fan air volume and wind pressure, the Internet has long been a search of a large number, is also a commonplace problem, but in the circle can make this problem clear really is very few...
