Formulation, finite-element modeling and winding factors of non-overlap winding permanent magnet machines

Abstract

The layouts, formulation and winding factors of iron-and air-cored non-overlap winding permanent magnet machines are considered in this paper. The winding formulation gives information about the use of negative periodical boundary conditions in the finite element analysis. Particular attention is given to air-cored non-overlap windings, with entirely different results regarding optimal slot-pole combinations.
