Abstract
Flux density in the air gap of an electrical machine is increased by varying the cross sectional area of conductors wound on the stator. Conductors of smaller cross sectional area are located within the air gap and conductors of larger cross sectional area are located outside the air gap. Because the smaller conductor allows the air gap to be reduced, air gap flux density is increased.
