Abstract

PURPOSE:To alleviate the mutual interference of an exciting current and a torque current and to stably control at the time of output voltage saturation by switching the compensation of an exciting current controller and a torque current controller at the time of an overload operation from a proportional integration to a proportional operation. CONSTITUTION:The maximum allowable torque current of a motor 3 is calculated by a motor current calculator 9 on the basis of a command signal from an exciting current instructing circuit 11, a frequency command signal omega1 from an adder 13, and an output signal V from the output voltage setter 8 of a cycloconverter. When a current command Iq from a speed controller 6 becomes a maximum allowable value or more, the compensation constants of second and third current controller 20, 21 are switched from a proportional integration to a proportional operation to alleviate the mutual interference of the exciting current and the torque current of the motor 3 and to stably operate a motor speed.
