ABSTRACT

This paper deals with the numerical analysis of a series of Permanent Magnet Synchronous Machines (PMSM) with the purpose to identify favourable combinations of the number of slots Z and number of poles 2p that lead to reduced values of Cogging Torque (CT) and Unbalanced Radial Forces (URF). The numerical analysis is carried out on PMSMs with 10, 12 and 14 poles and with a variable number of slots between 12 and 45. This study uses the field computation software package FLUX based on Finite Element Method (FEM), followed by analytical calculations for the estimation of URF.
