What is the stall protection function of the cooling fan?

Some customers have higher requirements for the reliability of the cooling fan. In addition to taking into account the abnormal power supply, dust, instantaneous power failure, and waterproof functions, the cooling fan is required to have a locked-rotor protection function. What is this function? The blocking protection function of the cooling fan is that when the external force forces the fan blades to stop, the current of the ordinary fan will be abnormally high at this time, causing the temperature of the cooling fan motor to become higher and higher, and finally may cause the driver chip to burn out as the cooling fan. The locked-rotor protection function is designed. No matter when and how long the fan blade is locked, it has no effect on the cooling fan, because as long as the fan blade is stuck and does not rotate, the motor will immediately lose power and stop working.
