    摘要: A motor control system controls to be constant a reactive power consumed by a motor load equipment having a motor to be driven by power supplied from an AC power source and a couple of thyristor converters for regulating the power supplied to the motor. To this end, the motor control system is comprised of a reactor power detector for detecting the reactive power of the motor load equipment, a command circuit for issuing a command to specify the rated reactive power consumed in the rated load running of the motor load equipment, and a reactive power control unit which receives an output signal from the command circuit and an output signal from the reactive power detector to produce a firing phase command signal depending on a difference between them. The firing phase command signal from the reactive power control unit is applied to an automatic pulse phase shifter to control the firing phase of the thyristor converters.

    摘要: A synchronous motor having multi-phase armature windings and a field winding is drived by a frequency converter. Actual torque is determined from a sinusoidal position signal representative of rotational position of the synchronous motor and the armature current. The actual torque value is compared with a command torque signal, whereby the armature current is controlled in dependence on difference or deviation resulting from the comparison thereby to cancel the torque ripple. Torque ripple can thus be suppressed to a satisfactory degree even at a low rotation speed of the synchronous motor.

    摘要: A control apparatus of a synchronous motor having armature windings and perpendicular field windings comprises a frequency converter of a cycloconverter which converts the frequency of an alternating current and supplies the converted current to the armature windings of the synchronous motor. On a shaft of the synchronous motor are installed a speed detector, a position detector, and a speed instruction circuit. The frequency converter is controlled in accordance with the outputs of the speed detector, the position detector and the speed instruction circuit. An alternating current excites the field windings, so that a field of magnetic force is rotationally generated. The direction of the magnetic field is determined depending upon the output of the speed detector.
