No no, what i mean is back-emf and self inductance are two diff things, right? The back-emf has to do with the stator spinning within the magnetic field of the rotor (visa versa) thats how the controller knows what position the rotor is in. self-inductance is the amount of energy stored in the winding, and because of the amount of inductance, that create a kick-back to the controller while trying to switch from one polarity to other to effectively make the rotor spin. Self-inductance does, as far as i know, increase the switching time of the controller.
