know Cooling fan Dead corner: which factors cause fan dead angle?

The so-called dead angle of fan means that the fan can not be started according to the specified voltage when it is placed at certain angles.

The fan wants to turn but does not turn;

The test method is to adjust the fan poles in order before Hall IC,

Then, the voltage is slowly raised until starting. If each pole is started before the specified voltage value, it is qualified,

If there is a high difference and the starting voltage exceeds the specified value, it is called the factor that affects the dead angle of the fan,

1: Uneven magnetization of each pole of rubber magnet

2. Hall IC sensitivity is too poor
