ABSTRACT:
A baffle system for routing cooling fluids through a dynamoelectric machine. The baffle system may include a locking cam mechanism for releaseably attaching a baffle to a stator assembly to substantially eliminate an annular air gap between a rotor assembly and a stator assembly. The baffle system may include a locking strip attached to a stator slot wedge to seal the locking cam mechanism and baffle to the stator assembly. In other embodiments, the baffle system may include a friction pad for sealing the locking cam mechanism and baffle to the stator assembly. The baffle system may also include a locking tool for simultaneously, or individually, moving the locking cam mechanism from an unlocked position to a locked position, or vice versa.
