Claim 4:
5. The motor control device as claimed in claim 1, wherein the target rotation speed comprises a first target rotation speed, which is a command value supplied from a superordinate control device and relating to the rotation speed of the motor, and a second target rotation speed,
the acquisition part acquires a current value of the second target rotation speed based on a difference between a current value of the first target rotation speed and a previous value of the second target rotation speed,
the speed control part performs the speed control, so that after the transition, the actual rotation speed of the motor becomes the second target rotation speed acquired by the acquisition part,
at the time of the transition, the correction part corrects the second target rotation speed based on a relation between the actual rotation speed of the motor calculated by the rotation speed calculation part and the first target rotation speed acquired by the acquisition part,
in a case where the second target rotation speed acquired by the acquisition part is corrected by the correction part at the time of the transition, the speed control part performs the speed control, so that the actual rotation speed of the motor calculated by the rotation speed calculation part becomes the second target rotation speed corrected by the correction part,
in a case where the second target rotation speed acquired by the acquisition part is not corrected by the correction part at the time of the transition, the speed control part performs the speed control, so that the actual rotation speed of the motor becomes the first target rotation speed acquired by the acquisition part.
