Provided is a motor control device which is able to control a speed and a torque of a motor at a high speed. The motor control device (10) comprises: a control unit (12) having a reference speed command generation unit (121) generating a reference sped command of a motor (4) generating rotation power; and a driving unit (11). The driving unit (11) includes: a speed correction amount generation unit (111) generating a speed correction amount for the reference speed command; a speed calculator (114) calculating a speed deviation between the reference speed command corrected by the speed correction amount and the measured speed of the motor (4); a speed deviation conversion unit (115) converting the speed deviation into a reference torque command of the motor (4); a torque correction amount generation unit (116) generating a torque correction amount for the reference torque command; a torque calculator (118) calculating a torque deviation between the reference torque command corrected by the torque correction am
