摘要：
Due to the fringing effect, magnetic flux in the air gap of the electrical machines is reduced. This leads to largered the effective air gap length. Currently, Carter coefficient is applied to compensate the slots effects. This coefficient is calculated with respect to the slots dimensions and air gap length, using Carter formulas and corresponding curves. These curves are taken by solving the two dimensional Laplas equation for voltage, and cannot be accurate (errorless) completely. Nowadays, using the FEM (finite element method) packages of numerical methods, slot effects on the air gap flux distribution are calculated carefully. In this paper using the Ansys package of FE these effects are studied. Using the results of these studies and comparing them with carter method, the carter coefficient is modified.
