ABSTRACT:
Rotor slot insulation for dynamoelectric machines having rotors with subslots including two slot armors, each extending in an offset manner to the transition between the rotor slot and subslot and into the subslot a distance sufficient to eliminate the need for a subslot cover and for providing a creepage path of sufficient length as to prevent creepage between slot windings and rotor iron.
