To provide a rotary electric machine controller that excellently controls a plurality of rotary electric machines by using arithmetic processing units whose number is smaller than the total number of rotary electric machines.
The rotary electric machine controller includes a voltage control function F3 for calculating each three-phase voltage command being a command of a voltage for driving each rotary electric machine, a current control function F2 for calculating each voltage command used in the voltage control function F3, and a task management function F1 that completes each execution of the voltage control function F3 for driving each rotary electric machine for each reference calculation period set to a prescribed period, completes execution of one current control function F2 in each rotary electric machine once in several times of the reference calculation periods, and completes execution of the current control function F2 of another rotary electric machine in the reference calculation period during which one current control function F2 in each rotary electric machine is not executed.
