Magnetic Paths in the Field (Stator) (Electric Motors)

Using the quarter-stator drawing in Fig. 4.60, the portion of the stator is divided up into seven magnetic paths. In order to determine the widths and lengths of these paths, the dimensions of four triangles need to be determined. All magnetic path widths are multiplied by 2 because this analysis is done on a per-pole basis and the dimensions being used are from a drawing of half of one pole. For the initial calculations, use Lstte = 1.0.
