  • Stator position adjustment method, motor drive device and stator position adjustment system
    Patent number: 8076892
    Abstract: A stator position adjustment method for a motor drive device that includes a motor case, a rotor shaft supported by the motor case in order to rotate a rotor inside the motor case, and a stator disposed at an outer circumference of the rotor concentrically with the rotor and having a configuration in which the stator is tightened and secured to the motor case by a tightening unit that tightens the stator along a rotor axis. The method includes the steps of setting a first tolerance range as a maximum tolerance range of a stator axis in which a first gap is formed between an outer circumference surface of the stator and an inner circumference surface of the motor case; measuring a position of the stator axis; and adjusting the position of the stator axis within the first tolerance range based on a measured position of the stator axis.
