ABSTRACT:
In the primary frequency control of an induction motor which controls the velocity by changing the supply frequency of the induction motor, the torque component current value is determined from the current value on the primary side of the induction motor, and the excitation frequency command corresponding to the torque component current value is determined by changing the velocity command value by the torque component current value. Based on the excitation frequency command, the voltage command is formed and supplied to the primary side of the induction motor, to drive the induction motor. The acceleration and deceleration of the induction motor is thus performed in which the adjustment of the excitation frequency depends on the change of the load inertia.
