...Andrezej Demenko; Ghislain Remy; Julien Gomand; Abdelmounaïm Tounzi; Pierre‐Jean Barre Purpose The purpose of this paper is to present an analysis of the force ripples of an open slot permanent magnet linear synchronous motor (PMLSM). A calculation procedure using 2D finite elements method (2D‐FEM...

...Federico Delfino; Andrea Manella; Paolo Molfino; Mansueto Rossi The application of the equivalent source methods for the numerical calculation of the total magnetic force acting upon a permanent magnet is proposed. These methods are formulated in terms of the external field, which allows...

...J.F. Charpentier; G. Lemarquand This paper deals with a way of computation of the mechanical behavior of permanent magnet synchronous couplings. This method is based on the calculation of the forces between the magnets of the device. The formulation of these forces is based on magnetic pole theory...
