Abstract: PROBLEM TO BE SOLVED: To provide a controller for multi-phase rotary machine that detects an angle error due to a fitting position shift of a rotation angle sensor with a multi-phase rotary machine mounted on an object of mounting.SOLUTION: A microcomputer as a controller for three-phase motor (multi-phase rotary machine) performs processing for calculating an angle error Δθ due to a fitting position shift, etc., of the rotation angle sensor fitted to a motor. Firstly, d-axis and q-axis current command values are set to 0 ampere (S00). Then the rotating shaft of the motor is rotated from outside (S10), and a phase current flowing by a counter electromotive voltage is detected (S30), and subjected to three-phase/two-phase conversion (S40). A controller outputs voltage command values Vq, Vd so that a current detection value reaches 0 ampere (S50). Angle error calculation means calculates the angle error Δθ on the basis of the voltage command values Vq, Vd (S70), and stores the error as an angle correction value (S90). Corrections are made thereafter by subtracting a correction value from the detection value of the rotation angle sensor.
