This work reviews and compares different airgap reluctance calculation approaches with experimental results, focusing on the Schwarz-Christoffel transformation. The modelling of the airgap reluctance in two dimensions is tested against FEM simulations for typical airgap geometries. Then, an approach to obtain the three-dimensional reluctance is shown, and the limited experimental data shown in previous works is expanded to validate the different airgap calculation methods in EE cores. For the case of pot cores, a geometrical transformation is proposed and validated, allowing the application of the Schwarz-Christoffel methodology to other common core geometries. [-]
