Title:
HELICAL AIR GAP WINDING STATOR
Document Type and Number:
Japanese Patent JPS60167641
Kind Code:
A
Abstract:
PURPOSE:To obtain sufficient reliability in an electromagnetic resistance performance by forming the bending rigidity of a support pin of the axial end side of a stator winding larger than that of the pin of the axial central side. CONSTITUTION:A stator winding 3 is supported by a support pin 6 made of a plurality of rod-shaped nonmagnetic materials inserted radially to a peripheral gap 5 formed at the intersection of phase strips 3a, 3b, and inner and outer cylinders 4, 2 made of a nonmagnetic material mounted on the inner and outer peripheral surfaces of the winding 3. The bending rigidity of the support pin 6a of the axial end of the winding 3 is formed larger than that of the support pin 6b of the axial central aide. Thus, the winding 3 is supported rigidly with substantially uniform strength over the entire length even at a shortcircuit defect time, thereby obtaining sufficient reliability on an electromagnetic force resistance performance.
