ABSTRACT:
A motor-controlling method includes the steps of: preparing a motor control device provided with a motor for moving an object to be moved and causing the motor to move the object to a target position by first accelerating the object and then moving the object at a constant velocity; storing in advance an acceleration-period power consumption value corresponding to a power consumption of the motor during the accelerating movement; storing in advance a current value of a current flowing through the motor when the object is moved at the constant velocity; detecting a time for which the object is moved at the constant velocity when the object is moved to the target position; calculating a constant-velocity-period power consumption value corresponding to a power consumption of the motor during the constant velocity movement of the object based on the time that has been detected and the current value; and calculating a power consumption of the motor for a period during which the object is moved to the target position based on the acceleration-period power consumption value and the constant-velocity-period power consumption value.
