Performance Analysis of Outer Rotor Synchronous Reluctance Machine with Different Number and Form of Flux Barriers Per Pole

This paper presents the electromagnetic design of a low power outer rotor synchronous reluctance machine. It is well known that the form and the number of flux barriers influence the electrical (power factor, saliency ratio) and mechanical (torque, torque ripple) performances of the synchronous reluctance machine. For this study has been investigated the influence of different number of barriers on different rotor pole. Also, the form of the flux barriers will be change for half of the rotor poles. To characterize the outer rotor synchronous reluctance machine magneto-static and transient-magnetic simulation are compute.
