چکیده
In this study, a magnetic field is analyzed using an analytical method and compared with the electromagnetic characteristics of 8-pole 9-slot 12-slot permanent magnet synchronous machines considering rotor eccentricity. The flux density back electromotive force (EMF) are derived perturbation theory theory. First, Fourier modeling performed through magnetization modeling, two analysis regions set based on several assumptions for applying method. Accordingly, governing equations in form Poisson Laplace equations. addition, undefined coefficients general solutions calculated appropriate boundary conditions, EMF air gap region definition vector potential. results obtained finite element experimental results. we perform torque eccentricity analyze ripple cases involving pole/slot combination.
