What is the reason why the cooling fan of high bay light does not turn when connected to the power supply?

The previous high bay light cooling fans often used AC fans. The 220V direct power supply can be turned. As long as the fan is a good product, this problem does not exist. However, the price of the 8025 AC cooling fan is much lower than that of the DC cooling fan. Therefore, some industrial and mining lamp manufacturers switch to DC cooling fans, but they often find that many fans do not rotate. What is the reason? Mainly the power supply for the cooling fan in the industrial and mining lamp. The constant current source is used to supply the DC cooling fan. The current of the DC fan is required to match the power supply of the constant current source, so that the cooling fan can operate normally, and vice versa. The fan will not turn. Therefore, for industrial and mining lamps that need to be equipped with a cooling fan, it is best to provide us with a power supply. We design the corresponding cooling fan according to the parameters of the constant current source, so that there is no problem of power failure.
