ABSTRACT:
An armature lamina for a dynamoelectric machine characterized by having a plurality of equally spaced winding slots formed around its periphery so that the winding-receiving gap, or mouth, of each slot is positioned near one side thereof, rather than being positioned at the center of the slot. In a preferred embodiment, the winding slots are divided into groups such that half of the slots have their respective mouths positioned adjacent the leading slot side while the remaining half of the slots have their respective mouths positioned adjacent the trailing slot side. This characteristic off-centered arrangement of the respective slot openings enables a maximum number of energizing windings to be positioned in each slot when the laminae are stacked on a spindle and wound with coils of insulated magnet wire to form a random wound armature. Alternative embodiments are provided for short pitch and double fly wound machines.
