  "textContent": "A control device is applied to a rotary electric machine system including a rotary electric machine having polyphase winding and an inverter that adjusts the phase current of each phase in the winding, and performs power control of the rotary electric machine using the inverter. The control device includes a current setting unit that sets phase current command values for each phase of the winding based on an electrical angle of the rotary electric machine and a d-axis current command value and a q-axis current command value of the rotary electric machine, a current control unit that controls the phase current flowing through each phase based on the phase current command values set by the current setting unit, and a determination unit that determines whether a heat generation request is present in the rotary electric machine system. When it is determined that a heat generation request is present and the rotary electric machine is in a rotational stop state, the current setting unit sets an AC d-axis current as the d-axis current command value in order to pass a phase current that alternates on both positive and negative sides through each phase of the winding, and sets a phase current command value based on the AC d-axis current.",
