摘要： A motor control apparatus includes a secondary-magnetic-flux-command calculating unit including a minimum-current-secondary-magnetic-flux-command calculating unit that calculates a secondary magnetic flux command for minimizing a current root-mean-square value due to a torque current and an excitation current and a PWM-signal generating unit that generates a torque current command for outputting a desired torque command and an excitation current command for outputting the secondary magnetic flux command, performs vector control such that a q-axis current, which is a detection value of the torque current, and a d-axis current, which is a detection value of the excitation current, respectively coincide with the torque current command and the excitation current command, and generates control signals for turning on and off a switching element in an inverter.
