This motor control device is provided with: a control unit which controls the number of rotations of a motor in accordance with a required number of rotations by implementing a first control which enables high-torque and precise control with respect to the motor, or a second control enabling more efficient control than the first control with respect to the motor; and a switching determination unit which, if an actual measurement value of the number of rotations of the motor is greater than a prescribed threshold value of the number of rotations, switches the first control to the second control. The switching determination unit further switches the first control to the second control if the actual measurement value of the number of rotations is not more than the threshold value of the number of rotations, and when a prescribed time has passed from a point in time at which the actual measurement value of the number of rotations matched the required number of rotations.
