Abstract
A motor control device controls a fan motor, and controls a motor speed so as to maintain a predetermined airflow value. For this, the motor control device includes an input terminal for inputting a first operation parameter indicating the motor speed or a second operation parameter indicating a motor torque. Moreover, the motor control device includes a motor-speed target value arithmetically-operating unit that calculates, using a predetermined airflow value and the motor torque, a necessary modified value for the motor speed at the predetermined time intervals. Further, the motor control device includes an output terminal that outputs an instruction speed of the motor based on the necessary modified value.
