Abstract

PURPOSE:To eliminate an armature voltage detecting circuit by starting a field control in accordance with the rotating speed signal of a motor. CONSTITUTION:A speed control circuit 5 produces a current command voltage Vm responsive to the deviation alpha between a speed command voltage Vac responsive to the depressed amount of an accelerator and a speed detection voltage Vg, and a current control circuit 7 controls a drive circuit 8 in response to the deviation (e) between the voltage Vm and a current detecting voltage Vi. A function generator 21 outputs a function voltage Vf responsive to the speed detecting voltage Vg, and a field current instructing circuit 11 outputs a signal Iil of the magnitude proportional to the deviation when the deviation gamma is gamma>0 between the voltages Vf and a field control starting voltage Vcs. A high voltage preferential circuit 14 applies larger current of the deviation between a signal Ii2 reduced by the signal Ii1 from the maximum strengthened field current Ifmax and the field current If and the minimum weakened field current Ifmin to a field current control circuit 16.
