Abstract

PURPOSE: To perform constant output control precisely by increasing the field current in response to a speed and a load current and by compensating the decrease in main magnetic fluxes due to demagnetizing action.
CONSTITUTION: In the case the constant output control of a DC motor 1 is performed, the speed control is achieved by the speed-feedback value from a speed generator 3, and the current feedback value from a current sensor 5 by a speed control circuit 8 and a current control circuit 7 based on the speed-command value specified by a speed setting adjuster 9. The sensed value of an armature-voltage sensor 6 and the command value specified by a field-voltage setting adjuster 14 are correlated, and the field current is controlled so that the armature voltage becomes constant. Said field current control is performed by a field control circuit 12 depending on the sensed value of the field current sensor 11. The actual value of the armature current and the actual value of the speed are input to a field compensation circuit 18 from the sensor 5 and the speed generator 3, respectively. The current command value of the field control circuit 12 is compensated by the output of the operation in the field compensation circuit 18, thereby the constant output control can be precisely performed.
