The paper presents an analytical method in order to obtain the electromagnetic field distribution in an axial flux slotted permanent magnet machine under no-load conditions. The method solves the Laplace equation in the gap of an slotted machine via magnetic scalar potential. Once the magnetic scalar potential is defined, the magnetic flux density components are computed.. Results issued from the proposed model are compared with those stemming from a 3D finite-element method (FEM) simulation. In addition to permanent magnet machines, this technique can be applied to any 2D geometry with the restriction that the geometry should consist of rectangular regions.
