Interphase Insulator

摘要

Electrically insulating material so foldable as to form an interphase insulator so configured as to be inserted in the slots of the stator or the rotor of an electric machine to prevent separate coils inserted in the same slot to be in direct contact with one another and to prevent the coil heads of different coils to be in direct contact is described herein. The interphase insulator may be so folded that the coil heads are properly insulated from one another.

主权项

1. An interphase insulator made of a insulating material and configured and sized to enter the longitudinal slot of an electric machine and to electrically insulate a first and a second coil from one another, the first and second coils each including two longitudinal legs and two opposite heads interconnecting the longitudinal legs; the interphase insulator comprising:
a longitudinal leg-insulating portion so configured and sized as to enter the longitudinal slot of the electric machine; and two head-insulating portions provided at opposite longitudinal ends of the leg-insulating portion; at least one head-insulating portion being provided with a first foldable tab so configured and sized as to align the head-insulating portion with the head of the coil.
