Abstract: A rotary electric machine system includes a rotary electric machine, first and second power-supply systems, a sensor, a first abnormality determination section determining whether an abnormality has occurred in a first armature-winding group, the first power-supply system, or the sensor, a second abnormality determination section that, on condition an abnormality has been determined, controls power output depending on a type of the abnormality, increases current flowing from the second power-supply system to a second armature-winding group when output torque due to current flowing to the first armature-winding group decreases, to increase output torque due to the current flowing to the second armature-winding group, and determines whether an abnormality has occurred in one of the first armature-winding group, the first power-supply system, and the sensor, and a prohibition section that, on condition that an abnormality has been determined, prohibits power supply from the first power-supply system to the first armature-winding group.

Abstract: A rotary machine control apparatus controlling a drive of a rotary machine that has multiple winding groups is provided. The rotary machine control apparatus includes electric power converters in multiple systems, a failure detection portion, and a control portion. An electric power converter has switching elements in an upper arm and a lower arm and converts DC power. The failure detection portion detects a failure of an electric power converter or a winding group. The control portion calculates a current command value and a maximum current limit value, and controls an output to the electric power converter. The control portion stops the output to the electric power converter in a failure system, and the control portion increases the maximum current limit value with respect to the output to an electric power converter in a normal system.
