Abstract

PURPOSE:To realize conservation of materials without generating local magnetic saturation at an iron core yoke section by forming a stator core with the same distance from the bottom sections of each slot having different depth to the external peripheral sections of the stator core. CONSTITUTION:The depth of slots 6b housing the windings located at the middle layer out of the windings superimposing in three layers is made smaller than the depth of slots 6a housing the windings located at the outermost layer and deeper than the depth of slots 6c housing windings located at the innermost layer. A circular arc-shaped section is formed respectively with the central section P of the iron core 10 as the starting point so that the distance from the bottom sections of each slot 6a-6c may be H. Furthermore, a circular arc-shaped section having a radius of H is formed with corner sections 9a-9c at the bottom sections of the slots 6a, 6b as the central figure to form external peripheral sections 8a-8c.
