Abstract
(EN)
One embodiment of this driving control device is a driving control device that controls the driving of a motor and comprises: at least two inverters that each supply power to the motor; and a control unit that selectively performs first driving control and second driving control, said first driving control causing both of the two inverters to operate to drive the motor, and said second driving control causing one of the two inverters to operate to drive the motor, wherein the control unit uses, as the operation of the one inverter during the second driving control, a first operation mode during a first temperature condition, and a second operation mode, which produces less heat than the first production mode, during a second temperature condition, in which there is less heat dissipation from the one inverter to the other inverter compared to during the first temperature condition.
