The DC cooling fan has two positive and negative power wires. When the cooling fan is installed, the positive and negative wires are connected reversely. Will the cooling fan burn out? Probably, this is mainly related to the IC design of the cooling fan factory
Generally, the driver IC of the double-wire winding method has internal protection design, and the positive and negative power lines are connected reversely, which shows a short circuit. At this time, the current of the cooling fan will be much higher than normal, and the motor current is large. The temperature rise is high. When the temperature reaches a certain level, the driver IC will be damaged due to overheating, and the cooling fan will be broken at this time.
A part of the single-winding driver IC has no internal polarity protection. If there is no polarity protection on the motor stator PCB board, it may burn the IC instantly when it is connected.
In order to prevent the cooling fan from burning due to the reverse polarity connection, it is best to add a diode to the PCB of the cooling fan to design polarity protection, so that the energized cooling fan is connected reversely and the current is zero, showing no power. Will never burn
