| description | There is provided a control apparatus of an AC motor (2) capable of performing stable torque control even over the entire running region of the AC motor. Structurally, a feedback control system (9, 8) for controlling the magnitude of motor primary current, a feedback control system (8, 17) for controlling the exciting component of motor primary current and a feedback control system (8, 18) for controlling the torque component of motor primary current are provided. Torque control is effected by a vector control system (4, 5, 6, 7, 8, 9) in the low speed running region and torque control is effected by a slip frequency control system (16, 10, 19, 20, 21, 22, 23) in the high speed running region, so that torque can be controlled excellently over the entire running region. |
