<P>PROBLEM TO BE SOLVED: To provide a motor driving device which can continue operating of a permanent magnet synchronous motor even at an instantaneous stop time, to provide a motor driving device which does not give a shock to the permanent magnet synchronous motor at the controlling time of the instantaneous stop time, and to provide a motor driving device which is easily to perform the gain control of a proportional item and an integrating item used to control a proportional integration. <P>SOLUTION: The motor driving device has a function of limiting an output power from an inverter circuit at the instantaneous stop time, and realizes the continuing of the operation of the permanent magnet synchronous motor by using a means for correcting a q-axis current command value. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
