Title: MOTOR CONTROL DEVICE
Abstract:
A motor control device is provided with: a secondary magnetic flux command computation unit (5) having a minimum current secondary magnetic flux command computation unit for calculating a secondary magnetic flux command (F2R) which minimizes an effective current value obtained from a torque current and an excitation current; and a PWM signal generation unit (9) which generates a torque current command for outputting a desired torque command (PTR) and an excitation current command for outputting a secondary magnetic flux command (F2R), performs a vector control so that a q-axis current (I1QF) which is a detection value for a torque current, and a d-axis current (I1DF) which is a detection value for an excitation current are respectively equal to the torque current command and excitation current command, and generates control signals (U, V, W, X, Y, Z) which turn on and off a switching element (16) provided on an inverter (11).
