A rotational electric machine includes: a stator configured to generate a rotating magnetic field by an alternating current converted from a power supply voltage of a battery; a rotor configured to rotate by the rotating magnetic field; a field coil configured to excite the rotor by a direct current converted from a power supply voltage of the battery; an acquisition unit configured to acquire the power supply voltage and an induced voltage of the rotational electric machine; and a power generation control unit configured to perform regenerative power generation when the induced voltage acquired is lower than a preset voltage equal to or lower than the power supply voltage acquired, and to perform alternator power generation by the induced voltage when the induced voltage acquired is equal to or higher than the preset voltage.
