Abstract
A rotational electric machine includes a stator configured to generate a rotation magnetic field in response to alternating current; a rotor configured to rotate in response to the rotation magnetic field; a field coil configured to excite the rotor in response to direct current; an acquisition unit configured to acquire manipulation information related to a torque generated by or caused to be generated by the rotor and a rotational state of the rotor; and a motor characteristic control unit configured to control the direct current based on the manipulation information and the rotational state acquired by the acquisition unit to control a motor characteristic.
