ABSTRACT:
Phase insulation for separating the end turns of the windings at the lead end of a stator core for a dynamoelectric machine and a method for the simultaneously inserting multiple sets of windings with the phase insulation into the stator core. The phase insulation is connected at its ends to form a continuous ring. The phase insulation includes openings along an edge combined with continuous portions between each opening and another edge. The openings and continuous portions allow the diameter of the phase insulation ring to contract while retaining substantially a ring shape without moving toward or away from the stator core and without tearing to maintain complete electrical separation of the different phase windings.
