Title:
モータ制御装置
Document Type and Number:
Japanese Patent JP7081274
Kind Code:
B2
Abstract:
To improve efficiency of vibration control for torque control in a voltage saturation region.SOLUTION: A motor controller includes a current command value generator that generates a current command value for a motor from a speed command value and a speed of the motor, and a determination unit that determines whether or not the current control region of the motor is in a voltage saturation region. In a case where it is determined by the determination unit that the current control region of the motor is in the voltage saturation region, the current command value generator generates the current command value for the motor on the basis of an intersection between a constant torque curve of the motor and a constant induction voltage ellipse of the motor.SELECTED DRAWING: Figure 2
