What is a cooling fan
u003cbru003e The operation of the cooling fan relies on the changing magnetic poles on the stator (generated by electromagnetic field), and the magnetic force generated by the interaction with the fixed magnetic poles on the rotor (fan blades) to push the fan to run. When the fan rotates, there is a set of two coils at the same time The fan is continuously operated by switching between the two sets of coils through the Hall IC. This kind of fan that can change the current direction without carbon brush is called a cooling fan. Wenling Tongchi Automobile Air Conditioning Manufacturing Co., Ltd. specializes in cooling fans.
