Abstract
A rotor slot insulation system includes two L-shaped insulative armors lining a slot that is disposed in the rotor for receving a conductor. The short legs of the insulative armors, which are disposed at the bottom of the slot, face each other and preferably abut. A spacer device overlays the short legs for spacing the conductor away from the corners of the armors and for increasing the electrical path from the conductor to the rotor. The spacer device and insulative armors may be secured by disposing a member, which is affixed to the spacer device, to engage the short legs of the insulative armors and to extend into a recess in the bottom of the slot. In a more preferred embodiment, the spacer device and insulative armors are extended beyond each axial end of the rotor body and a respective member is affixed to the spacer device beyond each axial end of the rotor body and radially inwardly extends to engage the respective axial end of the rotor body or a centrally disposed spindle for preventing axial motion of the spacer device and the insulative armors in the slot.
