To get a better design of electromagnetic devices, it is important to understand the relationship between core configurations and leakage flux distributions. The possibility of increasing weight and dimensions of electrical machines requires more and more care in the evaluation of magnetic field distribution. This paper presents a method for calculating the steady-state leakage flux distributions for electromagnetic devices. Finite element method (FEM) has been used to carry out the field behavior of permanent-magnet (PM) generator in terms of magnetic vector potential (MVP) A, as A is the preferred potential to obtain the field variables like magnetic field density (B) and magnetic field intensity (H). Then, fuzzy model of the generator is developed using adaptive neuro-fuzzy inference system (ANFIS), for carrying out its leakage field analysis. Performance is evaluated by comparing finite element model with fuzzy model, and good correlation is achieved between them.
