Abstract
A stator position measuring method and device relating to a motor driving device including a motor case, a rotor, and a stator disposed on an outer periphery of the rotor concentrically with the rotor, includes measuring a position of the stator relative to an axial center of the rotor, wherein the position of the stator is determined in a rotor not-inserted state, in which the stator is housed inside the motor case and the rotor is not inserted in the stator, by measuring a position of a radial surface of a stator core, which includes a magnetic body or a conductor forming the stator, relative to the axial center of the rotor using a non-contact displacement sensor that is selectively sensitive to the magnetic body or the conductor.
