A motor control apparatus includes a secondary-magnetic-flux-command calculating unit 5 including a minimum-current-secondary-magnetic-flux-command calculating unit that calculates a secondary magnetic flux command F2R for minimizing a current root-mean-square value due to a torque current and an excitation current and a PWM-signal generating unit 9 that generates a torque current command for outputting a desired torque command PTR and an excitation current command for outputting the secondary magnetic flux command F2R, performs vector control such that a q-axis current I1QF, which is a detection value of the torque current, and a d-axis current I1DF, 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 U, V, W, X, Y, and Z for turning on and off a switching element 16 included in an inverter 11. |
