A rotating machine control device comprises: a first inverter that applies an alternating-current voltage to three-phase windings of a first system included in a rotating machine, based on a first direct-current voltage that has been output from a direct-current power supply of the first system; a second inverter that applies an alternating-current voltage to three-phase windings of a second system included in the rotating machine, based on a second direct-current voltage that has been output from a direct-current power supply of the second system; a first controller; and a second controller, in that the first controller and the second controller each limit an own system voltage command related to a voltage to be applied to the three-phase windings of an own system by use of a direct-current voltage of an other system, in a case where a direct-current voltage of the own system is higher than the direct-current voltage of the other system, and also generate a value obtained by normalizing the own system voltage command by use of the direct-current voltage of the own system, as a command value to an inverter of the own system.
