N2 - This paper deals with the start-up analysis of a synchronous reluctance motors (SynRMs) with uniformly distributed cage bars in the rotor structure. Two SynRMs are modelled using 2D Finite Element Method (FEM). The rotors of both motors are built with stamped conventional steel laminations having flux barriers. The first motor model (SynRM1) has closed rotor slots above each flux barrier separated with magnetic bridges, and the second (SynRM2) is fitted with cage bars in the rotor air-barriers. The motors magnetic conditions are analysed under transients and steadystate operations. The Finite Element Analysis (FEA) results show that the SynRM2 has higher peak-To-peak accelerating torque, but has higher synchronization time. The results also provide that high steady-state average torque (Tave.) and lower torque ripple (Trip.) contents are achieved by the fitted with cage bars in the rotor air-barriers. Keywords - synchronous reluctance machine, flux-barrier, cage rotor bars, average torque, ripple torque.
