PURPOSE:To obtain a controlling method capable of stably operating a motor by setting the responding time constant of a field controller to an armature current to the upper limit value or lower. CONSTITUTION:The response of a field intensity to an armature current Ia is applied to a field controller 3 of a motor from the high speed response faster than the time constant determined by the four constants of the reduction rate of a field 2 by the armature circuit resistance, inductive component, counterelectromotive voltage and armature current Ia. In this manner, the magnetization reducing effect of the motor is compensated, and the operations, of single or a plurality of motors are always stabilized. |
