Zusammenfassung:	PROBLEM TO BE SOLVED: To improve precision in the control of the number of revolutions of a motor, in a motor control unit. SOLUTION: In this motor control unit, a motor 1, a current detector 3 and a current controller 2 which are interposed in a current supply path to the motor 1, and a current corrector 11 which outputs a current correction command to the current controller 2, on the basis of an output from the current detector 3 are installed. The current corrector 11 is provided with an A/D converter 7 in which the output from the current detector 3 is inputted, a storage device 13 storing the output of the A/D converter 7, and an operation part 14 operating an output from the storage device 13 and outputting the result to the current controller 2.
