摘要
In a vector control method for controlling a motor by detecting a primary current in a motor driven by an inverter circuit with an electric current detector, dividing the primary current detection value detected by the electric current detector to a current-for-torque detection value and a detected current-for-excitation detection value, and thus dividing a primary current instruction value to a current-for-torque instruction value and a current-for-excitation value, a portion between the current-for-torque detection value and current-for-excitation detection value each obtained from the primary current detection value is changed by an Iq gain circuit (gain Kqc) and an Id gain circuit (gain Kd), which are discrete circuits, and the rated torque characteristics of the motor is changed according to change of the apportion.
