Topology Exploration of Static-Excited Cylindrical Machines Using a General Analytical Magnetic Field Solution

An innovative approach, named topology exploration, is introduced in this paper. The aim of this approach is to help in the creation of electromagnetic devices, and to explore a priori unknown structures. In so doing, a general analytical solution of the magnetic field in static-excited cylindrical machines is developed, and then coupled to a stochastic procedure to determine if some structures are viable. The analytical model can account for variable boundary conditions, and hence, is suitable to determine electromagnetic performances of any structures. After 3 months of calculations, the topology exploration approach revealed interesting results showing the validity of the method.
