On the segmented rotor reluctance synchronous motor saliency ratio calculation

Abstract

The reluctance synchronous motor performance highly depends on its saliency ratio. Therefore an accurate analytical calculation of the motor’s saliency is quite a necessity within the designing procedure. In this paper an analytical method to calculate the main motor inductances and its saliency ratio is applied to a segmented rotor reluctance synchronous motor. The results obtained for two motor variants, compared with the ones obtained via a 2-D FEM computation and via tests, stand by to prove the proposed technique accuracy.
