The aim of this contribution is to assess the capabilities of a quasi-3D hybrid analytical model for the estimation of iron loss in axial flux permanent magnets machines. The hybrid analytical modelling (HAM) approach is based on a direct coupling of analytical solution of Maxwell's equations with reluctance networks (RN). The quasi-3D hybrid analytical modelling approach consists of dividing the...
This paper describes a new line-starting method of a class of synchronous motors. A general overview of line start synchronous machines is first presented. Problems related to the starting of these machines will be highlighted. Problems related to line starting of synchronous machines which do not have damping or squirrel cages will be particularly discussed. The proposed line starting method will...
This paper presents an analytical model for the prediction of the on-load magnetic field in axial flux semi-closed slots and surface-inset permanent magnets machines. The technique is based on 2-D exact solution of the Maxwell's equations in low permeability regions (slots, slot opening, airgap, permanent magnets adjacent to the airgap and moving armature slots) using the separation of variables method...
This paper presents an analytical solution for prediction of the magnetic field in slotted permanent magnet axial flux synchronous machines in the case of inter-turn short-circuit stator fault. The technique is based on 2-D solution of the Maxwell's equations using the separation of variables method. The magnetic field expressions are developed in slots regions, magnetic airgap region, slot opening...
