A drive device for a permanent-magnet synchronous machine has a power converter 102 that drives a permanent-magnet synchronous machine 103, and a controller 101 that controls the power converter 102. The controller 101 comprises: a torque correction unit 110 that corrects an inputted torque command value; and a current command calculation unit 111 that generates, on the basis of the torque command value corrected by the torque correction unit 110, a current command value for controlling driving of the permanent-magnet synchronous machine 103. The torque correction unit 110 corrects the torque command value on the basis of a value associated with the magnetic flux of the permanent-magnet synchronous machine 103, and the current command value generated by the current command calculation unit 111.
