Abstract

With respect to a first allowable range (Tr1) as the maximum allowable range of a stator axis (Zs) in which a first gap (g1) between the outer peripheral surface of a stator and the inner peripheral surface of a motor case is formed and a second allowable range (Tr2) as the maximum allowable range of the stator axis (Zs) in which a second gap (g2) between the inner peripheral surface of the stator and the outer peripheral surface of a rotor is formed, thee first allowable range (Tr1) is set to be same as or smaller than the second allowable range (Tr2). The position of the stator axis (Zs) is measured and is so adjusted that the position of the stator axis (Zs) obtained is kept within the first allowable range (Tr1).

Description

technical field [0001] The present invention relates to a motor housing, a rotor that is pivotally supported by the motor housing and rotates inside, and a stator arranged concentrically with the rotor on the outer periphery of the rotor, and the stator is tightened along the axis of the rotor by means of a A motor drive device fastened and fixed to a motor housing by fastening a unit, relates to a method for adjusting the position of a stator in such a motor drive device, and relates to a stator position adjustment system using the adjustment method. Background technique [0002] Recently, a so-called hybrid vehicle having an engine and a motor drive device as a driving source of an automobile has attracted attention from the viewpoints of fuel consumption and environmental protection. For this kind of hybrid vehicle, the motor drive device not only works as a motor that obtains power from the battery to generate driving force, and transmits its driving force to the side of...
