Abstract :
A finite element method is developed to evaluate cylindrical electromagnetic fields due to eddy currents inside linear conducting media. Boundary conditions are imposed in an integral form combined with Neumann conditions. The method is applied to a periodic system of slot embedded conductors in the rotor of an induction machine and is verified by comparison with an analytical method
