Abstract: A motor control device at least includes a speed control part for controlling a motor rotation speed. The motor control device includes a torque correction means for suppressing variation in torque constant due to individual differences of motors. In addition, the motor control device corrects the torque constant by using a correction torque coefficient calculated based on an unloaded speed when a fixed voltage is applied. Alternatively, the torque constant is corrected using the correction torque coefficient calculated based on the motor applied voltage when the motor speed is fixed.

Abstract: A motor controller of the present invention comprises units which obtain information indicative of a motor speed (ω) and information indicative of motor torque (T), an air flow calculation section which calculates an air flow (Q) of a fan based on the motor speed (ω) and the motor torque (T); and a speed command generation section which generates a speed command (ω*) of a motor such that the air flow (Q) coincides with the predetermined air flow command (Q*).
