Abstract
An electrical rotating machine having winding coils with turns disposed in a pancake configuration which spirals outwardly about the axis of rotation of the machine. The coils are interleaved circumferentially about the axis with uniform and smooth inter-coil spacing for placement of electrical insulation of the type suitable for high voltage applications. The spiral pancake coils when assembled provide a generally cylindrical winding configuration which is conducive to being well-supported by the stator shield.
