Abstract
A means for preventing harmful interlaminar electrical currents from flowing within the stator core of dynamoelectric machines is disclosed. By providing an insulation between the building bolts and the step iron portion of the stator core, current flow is inhibited in the event that a portion of the stator core is electrically shorted between adjacent laminations. Electrical communication between the building bolt and the stator core laminations is prevented by an insulated cylinder disposed about the building bolt and cooperatively associated with two layers of plates which are disposed on the two axial extremes of a preselected segment of the stator core laminations.
