Will the positive and negative poles of the DC cooling fan burn?

Release time:

2020-01-13

When the DC cooling fan has only two positive and negative power cords, the positive and negative wires of the DC cooling fan are connected in reverse during installation. Will the cooling fan cause burning? Please come and have a look at the editor! The DC cooling fan has two positive and negative power cords. When installing the cooling fan, the positive and negative lines are connected in reverse. Does the cooling fan cause burning? Perhaps, this is mainly related to the integrated circuit design of the cooling fan factory. Generally, due to the internal protection design of the two-wire winding drive integrated circuit, the positive and negative power lines are connected in reverse, resulting in a short circuit. At this time, the current of the cooling fan will be much higher than normal, and when the motor

The DC cooling fan has two positive and negative power cords. When installing the cooling fan, the positive and negative lines are connected in reverse. Does the cooling fan cause burning? Perhaps, this is mainly related to the integrated circuit design of the cooling fan factory. Generally, due to the internal protection design of the two-wire winding drive integrated circuit, the positive and negative power lines are connected in reverse, resulting in a short circuit. At this time, the current of the cooling fan will be much higher than normal, and when the motor current is large, the temperature rise of the motor itself will be high. When the temperature reaches a certain level, the driver integrated circuit will be damaged due to overheating, and the cooling fan will be damaged at this time
A portion of the single-winding driver IC has no internal polarity protection. If no polarity protection is designed on the motor stator printed circuit board, the integrated circuit may burn immediately.
In order to prevent the fan from burning out due to polarity connection, it is best to add diodes to the printed circuit board of the fan to design polarity protection. In this way, the energized fan is connected in reverse, and the current is zero, indicating that there is no electricity. Never burn the machine.
