摘要：The synchronous motor driving apparatus including position sensors provided in
the synchronous motor, a current polarity detection circuit for detecting the polarities ofthe currents in the respective phase windings of the synchronous motor, an inverterdriving the synchronous motor, a motor speed calculation unit calculating the rotationalspeed of the synchronous motor depending on the output signals from the positionsensors, a speed control unit outputting a first voltage adjusting component (q-axiscurrent command value Iq*) to cause the rotational speed of the synchronous motor toapproach a speed command value and a phase control unit outputting a second voltageadjusting component (d-axis current command value Id*) to cause the phase differencesbetween the phases of the position sensor signals and of the currents in the respectivephase windings of the synchronous motor to become a predetermined value.
