PURPOSE:To make the number of coupling section one each at both sides which is sufficient enough resulting in the simplification of the shape of an inter-phase insulation segment, by providing projections to prevent the fall-off of the inter- phase insulation segment at the junction part of the inter-phase insulation part and the coupling part. CONSTITUTION:In the inter-phase insulation segment 7 constituted of a pair of inter-phase insulation parts 4 and coupling parts 5, projections 6 are respectively formed at the junction part of each inter-phase insulation part 4 and coupling part 5. This projection 6 is checked on the inside of a longitudinal both end part 9a coming out from the slot of a slot insulator 9 so as to prevent the fall-off of the inter-phase insulation segment 7. This projection 6 may be retained also on the outside folded part 9a of the slot insulator 9. Thus, it is sufficient enough that one piece of the coupling part 5 is provided on both sides. Therefore, the shape is simplified, and the loading of the inter-phase insulation segment 7 is facilitated. |
