Hall effect sensor spacing

I have a 10 pole BLDC motor with three hall sensors spaced at 60 degrees.
Do I have to set the hall spacing somewhere in the library before using it?

Maybe you can ask @Marc_O (and read his recent thread) he has recently had some success placing hall sensors.

It is not necessary. It should work without nothing to change.

It is probably a 120° electrical command, even if mechanically these ones are at 60°.
In fact, the hall of the center is placed at 120° electrical.

You can know it in checking the pattern with a multimeter in output of the Hall sensors, and check the sequence 5>4>6>2>3>1(5 corresponding to 0-60° electric, and so on).

Best regards.
