Great way to count magnets in your motor...

[squarewheels]

I just installes a new KT controller but I did't know how to set the P1 value.
(gear ratio x magnets)

I stumbled upon this amazing video, explaining that you can count the magnets just by disconnecting the motor from the controller and then simply short 2 of the 3 fases.

In my case for example, I counted 240 steps and after setting P1=240, everything was OK!
