DC fans (direct current fans) have little contact with the general public, but they are everywhere. They are mainly used in computers, communications equipment, medical machinery, home appliances and other industries. CFM-4020V-170-255-20 is a type of DC fan. Let’s see its application field and working principle.

Application field

CFM-4020V-170-255-20 can be used in a variety of industrial applications, mainly as exhaust fans, cooling fans, blower fans and so on. It is suitable for some special equipment with narrow space. It is small in size, but it is equipped with strong air volume and air pressure. The fan has good heat dissipation performance, excellent structural design, long service life and reliable operation. In addition, it is shock-proof and vibration-proof, which ensures the safety of the equipment. Moreover, its low speed, low noise and low electricity feature make it extremely energy efficient. Apart from the electrical requirements, this type of DC fan also meets the requirements for modern industrial systems.

Working principle

The CFM-4020V-170-255-20 DC fan is driven by electronically-controlled motor. In operation, the current passing through the motor\'s two wires creates a rotating magnetic field in the air gap of the motor. That rotating magnetic field then causes the motor spindle to rotate, which in turn causes the fan blades to rotate. The rotation of the fan blades creates air flow, providing ventilation or heat dissipation.

In addition, the speed of the motor can be set by a signal sent from the control circuit. By adjusting the pulse width of the signal, the rotating torque produced by the motor can be changed, thus controlling the speed of the fan to meet the necessary heating and cooling requirements of the application.

In conclusion, CFM-4020V-170-255-20 is a type of DC fan that is suitable for a variety of industrial applications. It has good heat dissipation performance, reliable operation, and it is shock-proof and vibration-proof. Its working principle is that the current passes through the motor\'s two wires to produce a rotating magnetic field, which drives the motor and makes the fan blades rotate. The speed of the motor can be adjusted by the signal sent by the control circuit.
