Patent ID: 7714477

Claim:
A support structure as vibration prevention to join a stator core to a stator frame in the rotating electric machine, comprising: a first ring-like support plate attached to an outer peripheral side of the stator core; a second ring-like support plate attached to an inner peripheral side of the stator frame; a third ring-like support plate attached to one of the outer peripheral side of the stator core and the inner peripheral side of the stator frame, and support bars extending through the first ring-like support plate, the second ring-like support plate and the third ring-like support plate so as to join the stator core and the stator frame, wherein: each of the support bars has a circular sectional shape at a portion where the support bars extend through the third ring-like support plate, and the sectional shape is selected from one of elliptic or rhombic at portions where the support bars extend through the first and second ring-like support plates, so that stiffness in the circumferential direction of the stator core is greater than that in the radial direction, and the circular sectional shape of each support bar has a diameter smaller than the hole of the third ring-like support plate to restrain the support bars from excessive deformation in an arbitrary radial direction thereof.
