Abstract

PURPOSE: To prevent corona from generating between the high resistance shield tape and the low resistance slot liner arranged on the circumference thereof by inserting a low resistance ribon inside the tape to better the contact therebetween.
CONSTITUTION: A high resistance shield tape 7 is wound around the circumference of an insulating layer 6 of the stator coil 3. Then, the tape is further equipped with a slot liner 8 and inserted into a slot. Prior to it, a low resistance ribon 12 is inserted inside the high resistance shield tape 7. The low resistance ribon 12 is arranged on the stem of the coil at least as illustrated by numeral 12a and combined with a short ribon strip 12b up to the coil angular section. With such an arrangement, a better contact between the high resistance shield tape 7 and the low resistance slot liner 8 equalizes the potential therebetween thereby preventing corona from generating therebetween.
