    • A controller for a motor carries out field weakening control by using a simple construction to change the phase difference between two rotors, which are disposed around a rotating shaft, without depending on the number of revolutions of a motor. The controller for a motor includes a field weakening current calculator for calculating a field weakening current command value on the basis of the radius of a target voltage circle, a d-axis voltage command value, and a q-axis voltage command value, a rotor phase difference command value determiner for determining a command value of a rotor phase difference on the basis of the field weakening current command value, and a current command value determiner for determining a d-axis current command value and a q-axis current command value on the basis of the rotor phase difference command value and a torque command value.
