In a rotating electric machine control device, a voltage command value calculation section calculates a voltage command value based on a current command value and a motor current. An inverter power estimation section estimates an inverter power based on the motor current. A power supply current estimation section estimates a power supply current based on the inverter power and a power supply voltage. A limit gain determination section determines a limit gain based on the power supply current and a target power supply current. A limited voltage command value calculation section calculates a limited voltage command value based on the voltage command value and the limit gain. A current limitation section is capable of limiting the power supply current by outputting a command value corresponding to the limited voltage command value to an inverter portion.
