Abstract
This paper investigates cogging force in a linear Transverse Flux Machine, TFM. 3D-FEM and
2D-FEM simulations has been performed and also two analytical methods have been applied. The analytical
methods are based on the reluctant pressure method. Once the ¯eld distribution on the side of the tooth is
known, the cogging force can be calculated by integrating the ¯eld. The agreement between the 2D-FEM
and Conformal Mapping, CM, analytical method is good. However the 3D-FEM simulation results indicates
a lower cogging force than the other two methods.
