FFB0412SHN

DC Fans, the motor of a fan usually consists of stator and rotor, in which the stator is made of iron core and is wound with the coil. The rotor is made of permanent magnet or iron. The operation principle is that when the current through the winding, the lines of the magnetic field and the conductor being generated, the rotor will produce the interaction along with the magnetic field line, then a torque is generated. This torque drives the rotor rotating and thus the fan starts working.

FFB0412SHN is a popular DC fan model. Its main application field is cooling system. For example, the fan is used to provide airflow and exchange thermal energy in computers, automotive parts and power supplies. The version of FFB0412SHN included in the product line of MEAN WELL offers an operating temperature range from -10 to 70°C, a maximum air flow of 35.7 CFM, and an MTBF of the fan of 70,000 hours. Besides, FFB0412SHN is equipped with a brushless DC motor to get long life cycle, low noise, and high stability.

In order to use the fan more efficiently, we need to understand its working principle. When a motor is powered, the stator winding will generate an electromagnetic force to drive the rotor to rotate. In FFB0412SHN, the elelctromagnet is fixed while the rotor rotates around it. The magnetic field generated by the stator will interact with the permanent magnet inside the rotor, forming an energy conversion loop for the motor. When the current flows through the stator winding, the magnetic field force created by the winding interacts with the permanent magnet in the rotor to maintain the circulation process, thus, producing the motor torque to drive the fan to rotate.

To achieve high performance and efficiency, the three main components of the motor - stator, rotor, and the magnet - need to be designed for utmost compatibility. For instance, the stator winding has to match the type of motor to provide the right amount of current; the rotor should have a permanent magnet that works well with the stator’s magnetic field; and the magnet inside the rotor should be carefully designed to provide maximum force for the motor.

In conclusion, the FFB0412SHN is a popular DC fan model with wide application fields, such as cooling system, computers, automotive parts and power supplies. It is equipped with a brushless DC motor for improved performance and longer lifespan. Understanding its working principle can help us use the fan more efficiently and effectively.
