A drive controller according to an aspect controls drive of a three-phase motor, and includes an electric value calculation unit that calculates an electric value in each of coordinate axes of rotating coordinates of the three-phase motor based on an electric value that is at least one of a current value and a voltage value generated in the three-phase motor, and a fault determination unit that determines a fault phase having a fault in phases of the three-phase motor by combining positive-negative information on at least one of a difference between a calculation electric value calculated by the electric value calculation unit and a target electric value indicating a control target of an electric value in each of the coordinate axes, and a variation of the difference, with each of the coordinate axes.
