Abstract

PURPOSE:To enable the effective use of a current supplied to a motor at the maximum limit by controlling the speed with a minor loop of a torque control under the control of the phase of a power source side and controlling the power factor under the control of the phase of the motor side. CONSTITUTION:When a current is supplied from an AC power source and the primary frequency of a motor 5 is controlled by converters 1, 3, the speed of the motor is controlled with a minor loop of a torque control or a current control under the control of the phase of the power source side, and the power factor is controlled under the control of the phase of the motor side. Or, a motor terminal voltage is controlled under the control of the phase of the motor side. For instance, a synchronous motor 5 is controlled in the manner as above with a circuit shown, which includes a delay power factor torque detector 4, a speed setting regulating resistor 10, a torque controller 15, a power source side phase controller 16, a torque direction detector 17, a delay power factor setting regulating resistor 18, and a motor side phase controller 23 and so forth.
