Estimating the term…
A motor control device having a motor temperature sensor for detecting a magnet temperature of the motor, a magnet magnetic flux calculation section that calculates a magnet magnetic flux of the motor corresponding to the magnet temperature of the motor, a current combination candidate calculating section that calculates a d-q axis current combination candidate that minimizes the input current of the inverter within a voltage limit ellipse determined by a value that can be output by a voltage of a power supply of the motor, and a d-q axis current search section that searches the d-q axis current that minimizes the input current of the inverter within the range of the combination candidate of the d-q axis currents when the d-q axis current of the motor moves on a voltage limiting ellipse by automatic weakening flux control.
