PROBLEM TO BE SOLVED: To provide a rotary electric machine controller which can deal with occurrence even of an emergent abnormal condition leading to dangerous abnormal condition if it is not recovered immediately. SOLUTION: The rotary electric machine controller comprises a plurality of upper arm switching elements 6 connected between a plurality of stator winding terminals of a rotary electric machine 2 and high potential of a battery 3 in order to perform powering or power generation, a plurality of lower arm switching elements connected between the plurality of stator winding terminals and low potential of the battery 3 in order to perform powering or power generation, and a section 13 for controlling the powering or power generation by turning the plurality of upper arm switching elements 6 and the plurality of lower arm switching elements 7 on/off, respectively. When a plurality of faults occur in the rotary electric machine controller (ISG) 1, the control section 13 performs protection against any one of the plurality of faults preferentially.
