PROBLEM TO BE SOLVED: To provide a rotary electric machine control device capable of properly performing control on the basis of a current of a power storage device even when an intermittent drive control of a converter is performed.SOLUTION: A rotary electric machine control device 40 includes rotary electric machines 30, 32 connected to a power storage device 12 via a converter 16, and controls the operation of the rotary electric machines 30, 32 and performs the charge/discharge of the power storage device 12 on the basis of a battery current value Iflowing in the power storage device 12. The rotary electric machine control device 40 performs the intermittent drive control of the converter 16 of stopping the operation of the converter 16 when the battery current value Iis equal to or less than a predetermined threshold current and the output voltage of the converter 16 is equal to or more than a threshold voltage. When the control period of the intermittent drive and the sampling period of the current value of the power storage device coincide with each other within a predetermined range, the threshold voltage is changed.
