Method and apparatus for fabricating vent plate having bow-tie slot arrangement |
摘要 |
A vent plate for supporting a finger having a rivet portion is disposed intermediate adjacent core laminations in a dynamoelectric machine. A plurality of finger members secured to the vent plate cooperate with the core laminations to define a ventilation duct for circulation of a cooling gas through the core. The vent plate has a plurality of slot openings arranged to receive the rivet portions of each finger. The vent plate slots are characterized by a bow-tie outline defined by intersecting planar and curved side surfaces which permits variable orientation of rivet portions through a predetermined angular range.
