Abstract
A rotating electrical machine includes a DC power supply; a rotating electrical machine; an inverter provided between the DC power supply and the rotating electrical machine to control current flowing in the rotating electrical machine; and a control device that: determines a rotational speed as a rotational speed requested for the rotating electrical machine and a requested torque as a torque requested for the rotating electrical machine; and limits a torque of the rotating electrical machine. The inverter is operated based on the rotational speed and the requested torque determined by the control device, and the control unit changes a limit of the torque in accordance with an inverter voltage which is a voltage applied to a frequency conversion portion provided in the inverter.
