Abstract
The present invention provides an improved model and methodology for simulating motor performance which allow increased control accuracy at the higher currents, higher speeds, and/or higher current change rates required in modem mass storage devices. In addition, the invention provides methods for simulating motor performance, and for testing a motor commutation scheme. The model includes a plurality of phases extending between first ends joined at a center tap and second ends extending outward from the center tap to a corresponding plurality of phase taps, and a mutual inductance component disposed between two of the phases, wherein the mutual inductance and/or the phase inductance components may be a function of rotor position and/or current.
