A rotary electric machine system includes: a rotary electric machine; a lubrication mechanism configured to supply lubricating oil to a bearing of the rotary electric machine; and a control unit configured to control the supply of lubricating oil from the lubrication mechanism. The control unit is configured to acquire an operation status of the rotary electric machine and determine whether there is a possibility of occurrence of electrolytic corrosion in the bearing. The control unit is configured to, when it is determined that there is a possibility of occurrence of electrolytic corrosion, increase the supply of lubricating oil to the bearing by controlling the lubrication mechanism as compared to the supply of lubricating oil to the bearing at a time when it is not determined that there is a possibility of occurrence of electrolytic corrosion.
