Abstract
A motor control device which controls a motor for driving a blower unit, comprises a torque command generating section which obtains a motor speed of the motor and generates a torque command which causes an air flow of air supplied from the blower unit to coincide with a target air flow; wherein the torque command generating section is configured to calculate the torque command as a product of a polynomial of variables derived by dividing the target air flow by the motor speed, and a square of the motor speed.
