ABSTRACT:
A pancake armature winding in which the turns of each phase coil are insulated to withstand turn-to-turn voltage potential has phase-to-phase insulation provided by inner and outer insulative skins which act cooperatively with insulative filler pieces which also provide mechanical support for the phase coil. The reduced amount of insulation on each turn of the phase coil permits the overall size of the pancake coil to be reduced. The armature winding is supported mechanically by inner and outer insulative cylinders.
