Abstract
A corona suppression apparatus for a dynamoelectric machine having a stator coil (12) covered with a corona suppression covering (16), the apparatus including a member (10) conducting to ground (20) abutting a top layer (28) of the corona suppression covering proximate an overlap region (18) of the corona suppression covering. The member may be positioned in a gap (30) between the stator coil corona suppression covering and a stator core clamping finger (24) extending from the stator core proximate the stator coil. The member may also be configured to exert a compressive force on the overlap region by being compression biased between the corona suppression covering and the stator core clamping finger.
