ABSTRACT:
A resolver reference position adjustment method is capable of minimizing a detection error in the rotation angle of a rotor of a motor. In the resolver reference position adjustment method in which a reference position of a resolver of an axial double angle n mounted on an end of a shaft, to which the rotor of the motor is fixedly attached, for detecting rotation angles of the rotor is adjusted with respect to the rotor, the reference position of the resolver is adjusted by using the rotation angles of the rotor at a first point and at a second point, respectively, which are positions of the rotor apart an angle of (mechanical angle 180/axial double angle n) degrees from each other.
