MXUS Hall sensor as speedometer

[elt93]

Hi Guys,
Just got a MXUS 3000 and want to program a speedometer to work with it. I'm wondering how do this motor's hall sensors work, in which sequence and how many activations per rotations?
Thank you for your help!

The MXUS 3000W motors have 46 magnets. (23 Pole Pairs)

If you are using a Cycle Analyst, this is really easy to set up. Just program the CA for "23 Pole Pairs" and the appropriate tire circumference. The CA uses one of the hall sensors in this exact manner to determine the rpm of the motor, and calculate speed accordingly.

I'm trying to do my own analyst with an Arduino! So what you mean is I can take only one hall sensor and it will activate/deactivate 23 times in one revolution?

That's right.
