PROBLEM TO BE SOLVED: To provide a device for controlling a rotary electric machine capable of quickly switching between power running and power generation while suppressing rapid torque fluctuation.SOLUTION: Disclosed is a control device 14 which controls a rotary electric machine 17 which performs power running and power generation based on energization to a filed winding 12. This control device includes: a current control part for controlling a current made to flow through the field winding based on a torque command value which is a command value of torque generated by the rotary electric machine; a field current acquisition part for acquiring the field current flowing through the field winding; and a torque limit part which limits the torque command value within a range of a predetermined torque including zero until the field current acquired by the field current acquisition part becomes smaller than a predetermined current when switching between power running and power generation of the rotary electric machine and which releases the limit of the torque command value when the field current acquired by the field current acquisition part becomes smaller than the predetermined current.SELECTED DRAWING: Figure 1
