On the Carter's Factor Calculation for Slotted Electric Machines

Abstract

The air-gap flux density in a single side slotted unsaturated machine is computed via two dimensions finite element method (2D-FEM) and via some analytical approximations. The Carter's factor values are calculated using different equations and a comparison between the obtained results is presented, allowing for pertinent conclusions concerning the flux density analytical estimation or the Carter's factor calculation.
