　　The bracket cooling fan is an important cooling device for modern industrial machinery. It has good cooling effect, long service life, simple structure, and convenient installation. So do you know what a bracket cooling fan is?

　　What is a bracket cooling fan?

　　The bracket cooling fan is mainly composed of rotors, stators, fan blades and other auxiliary components. There should be many semiconductor components in the control circuit. Now they have been stored in one or more ICs. Many manufacturers have specially designed and manufactured many types of control motors. The IC is designed for use by fan circuit designers. Different types of IC control circuits are different, but the main purpose is to provide the effective function of the coil and the fan-related characteristic requirements for more effective control and protection.

　　The working principle of the bracket cooling fan:

　　Through DC voltage and electromagnetic induction, electrical energy is converted into machinery to drive the fan blades to rotate. In simple terms, it is the cooling device that relies on the continuous switching of coils and ICs, and the induction magnetic ring drives the fan blades to rotate.

　　The advantages of the bracket cooling fan:

　　1. The bracket cooling fan adopts the most advanced design, which has the characteristics of large air volume, low noise, long life and corrosion resistance.

　　2. Using high-quality bearings, silicon steel sheets, and enameled wires, it has higher reliability.

　　The monitoring methods of the bracket cooling fan itself are as follows:

　　There are two types of monitoring methods for the cooling fan of the bracket itself: alarm sensor and speed sensor. Using the alarm sensor, an alarm signal can be given when the fan speed is lower than a certain threshold value, and the speed signal output can realize real-time monitoring of the fan speed. . Obviously, the larger the air volume, the higher the cooling capacity of the bracket cooling fan. This is because the heat capacity ratio of the air is constant, and a larger air volume, that is, more air per unit time, can take away more heat.

　　The speed signal output from the cooling fan circuit of the bracket is usually in the form of pulses. Each wave head indicates that the fan has rotated one circle. Such a signal can be directly provided to the host through the data bus for display. The speed signal output by some fans is not the real speed of the fan, but a multiple of the speed. For example, 2, 4 or 6 pulses are generated per revolution, which must be processed to form the true speed signal reflecting the fan.
