摘要： PROBLEM TO BE SOLVED: To solve the following problem associated with conventional stators: during a withstand voltage test, the electric field of a through bolt and a nut is increased and large discharge is produced and as a result, the withstand voltage test may be incapable of being continued any longer or an electric field relaxation layer for preventing creeping discharge, installed on a stator coil may be damaged (to cope with this, those obtained by smoothly covering the thread of a screw with a conductive material or those obtained by covering a through bolt or a nut with an insulating barrier have been proposed).
SOLUTION: A stator includes: a stator coil housed in a slot in a stator core and having coil ends protruded from both end faces of the stator core; a fastener constructed of a through bolt and a nut screwed to an end of the through bolt and integrating the laminated steel plates of the stator core; and a cap-like insulating barrier covering this fastener and shielding the fastener from the coil ends. A conductive layer is formed on either or both of the inner circumferential surface and the outer circumferential surface of the cap-like insulating barrier. This conductive layer and the fastener or the stator core is electrically connected with each other.
