A brushed axial fan is a type of electric fan that consists of a rotor with blades that rotate around a central axis, and a stator with wire windings that produce a magnetic field. The rotor is powered by a motor that uses brushes to transfer electrical energy to the windings in the stator.
Fan blades are designed to move air parallel to the axis of rotation, creating airflow in the direction of fan movement. Brushed axial flow fans are usually used for heat dissipation of automobile water tanks. Generally, they need to work together with heat exchanger. And the fan speed can be adjusted by the temperature sensor. Like that the fan will work at different speed when the water tank temperature different which will provide more efficient and energy save working.
However, brushed axial fans have some disadvantages compared to other types of fans. They require regular maintenance to replace the brushes, which can wear out over time. They also produce electromagnetic interference (EMI) that can disrupt nearby electronic devices. Finally, they are not as energy-efficient as brushless axial fans, which use electronic controls to regulate the motor and do not require brushes.
