DC fan, also known as DC brushless fan, utilizes the theory of electromagnetism. DC brushless fan has an explicable overall structure, composed of brushless DC motor, blades and fan frame. The main feature is that the fan uses three-phase winding excitation, and the control circuit is connected to the internal rotor of the fan to generate a rotating magnetic field. By changing the direction of rotation of the magnetic field, the fan can achieve changing direction of air flow.DC brushless fans, such as CFM-A225V-131-445-11, have many different application fields.

Application in Household Appliances

CFM-A225V-131-445-11 DC brushless fan is usually used in household appliances. It is usually used as the cooling fan in electric cooker, water heater and air conditioner, and in vacuum cleaner, electric hair dryer, electric kettle, etc. Inside these appliances, the DC fan can dramatically increase the cooler airflow and provide better heat dissipation, making the appliance run more efficiently and safely. In addition, CFM-A225V-131-445-11 DC brushless fan can also be used as blower to clean dust particles and dead corners in the room, which can make indoor air more fresh and healthy.

Application in Automotive Industry

CFM-A225V-131-445-11 DC brushless fan can provide air cooling in all types of automotive electronics, such as automotive batteries, electric vehicles, engine control units, air conditioners, etc. The cooling fan can effectively cool the heat generated by the electronic components and, at the same time, produce a relatively low noise. The speed of the DC fan can also be regulated accurately by the control of the fan’s PWM signal.

Application in Industrial Systems

CFM-A225V-131-445-11 DC brushless fan can also be used in many industrial systems to supply the air for cooling purposes. In many machines, CFM-A225V-131-445-11 DC brushless fan can be used to reduce the friction. For example, the brushless fan can be used in packaging machines to provide cooling air for bearings and other parts. It can also be used in computer numerical control (CNC) machines, as well as in communication equipment, etc.

Working Principle of CFM-A225V-131-445-11 DC Brushless Fan

CFM-A225V-131-445-11 DC brushless fan is composed of three main parts, namely, the motor, the blades, and the fan frame. It works by using the electromagnetic force. Inside the brushless fan, there are small magnets mounted in the stator. The rotor is usually made of soft iron plates. When a current is applied to the stator, the alternating magnetic field will produce an electromotive force in the rotor, which creates a torque, which will in turn make the rotor spin. The blades attached to the motor will rotate as well, producing an airflow.

CFM-A225V-131-445-11 DC brushless fan can effectively control the air flow speed and noise by using an integrated motor control IC. By adjusting the duty cycle of the control IC, the energy delivered to the motor can be regulated, thus resulting in the changes in air flow speed. This makes the DC brushless fan ideal for many different applications. It also provides high efficiency and low noise performance, making it a great choice for many important applications.
