Abstract :
A method for analyzing 3-D magnetic fields and currents in electrical machines excited from voltage sources has been developed. It was obtained by expanding the 2-D finite-element method into three dimensions, using the A φ method. The basic idea and the finite-element formulation are described. The effectiveness of the method is shown by some application examples
