Abstract
Rectangular conductor wires are often used in alternator applications requiring a high slot fill to maximize output and efficiency. However for lower output and efficiency applications, round conductor wire may increase cost competiveness in these alternators. A common lamination for a core alternatively accommodates both rectangular conductor wires and round conductor wires for different applications without any other component changes. The lamina has a slot that aligns round wire in a single row within the slot and provides a predetermined clearance from the slot opening. A stator core formed from these laminae has a relatively high slot fill factor when wound with the round wire. The same stator core can be alternatively wound with square wire to increase the slot fill factor even higher. The common lamination results in two stator configurations: a high slot fill version (round wire) and a very high slot fill version (square wire).
