bldc commutation

Hi,

I have an 4 poles BLDC motor controlled with the help of a 3-phase inverter and quadrature encoder feedback. Is there a difference in the commutation sequence when the motor counts 4 poles instead of two?

The "classical" sequence would count six steps distributed equally along 1 mechanical cycle (1 revolution). I know that the sequence will still count the same steps, but should it be distributed along 1/4 revolution?

Thanks,

CyBeRbLaK
