Bibliography: leaf 54.Beginning with the developed version of a shaded pole motor a contour of the area concerned is defined which follows the boundary between rotor iron and rotor conducting medium, the pole gap, figure 1. In this case the analysis is restricted to a region which is given in y-direction as the distance between rotor –and stator iron over half a pole pitch in x-direction. Due to the shading ring it is not possible to define boundary conditions for the contour parts along the pole –and the pole-gap axi
