    • A rotating electrical-machine control system is provided with: a rotating electrical-machine comprising a rotor further comprising permanent magnets that are divided into a dividing-number of sections; an inverter circuit that drives the rotating electrical-machine by PWM control, using a carrier wave having a carrier frequency; a storage unit that has stored therein a relationship file that indicates the relationship between the dividing-number of the magnets, the magnet temperature, and the carrier frequency; and a control apparatus. The control apparatus comprises a condition acquisition processing unit for acquiring the target magnet temperature, a rotational-speed acquisition processing unit for acquiring the rotational speed of the rotating electrical-machine, and a carrier-frequency setup processing unit for providing the dividing-number of the magnets and the target magnet temperature to the storage unit and conducting a search therein, and giving the corresponding carrier frequency to an inverter control unit as an instruction.
