After extensive testing, I have come to the conclusion that the Hall Sensor on one of my motors must be faulty. It is encoding the movement of the magnetic disk 1,5x the actual speed.
These are the motors I am using:
Does anyone have experience with changing the Hall sensor? Would it be possible to desolder it and put a new one? I had asked in a local electronics shop, and they told they haven’t seen a 4-pin Hall Sensor as the one on the motor before.
I would also need help identifying the sensor… There are numbers on it, that I noted down:
I cannot find anything according to these numbers online… Maybe it’s possible to measure the current on the single pins… ?
Any help on this is very much appreciated!
