Magnetic field analytical computation in synchronous reluctance machines considering the iron saturation

This paper deals with an analytical model of REL motor considering the stator slotting effect and the magnetic saturation in the stator and rotor iron paths. It joints the field distribution at the air-gap to a lumped-parameter magnetic network. As an example, 36-slot 4-pole machine is analyzed, considering three flux barriers per pole. Finite element analysis confirms the results achieved by means of the analytical model.
