A motor driving apparatus has a driver circuit configuration capable of individually adjusting three phase coil currents. Coil current waveforms are formed to have a total of three phase shaft direction forces to be zero in compliance with predetermined mathematical expressions, and thus, three phase coil current profiles can be made independent of one another, and vibration-causing factors attributed to the fact that a certain phase is in an non-energized state are corrected by adjusting the current profiles of the other phases. Consequently, the vibration and the noise can be reduced.
