Hall has three wires (the pins are defined as: the seal faces itself and the pins face down. From left to right, it is 1 positive power supply, 2 negative power supply and 3 output (signal).
It's on! Turn the motor manually once, and Hall's feet 2 and 3 will output high and low voltages! (The high voltage is approximately equal to the Hall power supply voltage, and the low voltage is approximately equal to 0. If the voltage is constant or there is no output! Then Hall was destroyed!
I'm a hall producer! Oh, the series pavilion!
I hope I can help you!
