Torque-angle characterization of a Synchronous Reluctance Machine

This paper presents torque-angle characterization of a Synchronous Reluctance Machine (SynRM). Advancement in power electronics and machine design have allowed these motors to be used in various industrial and traction drive applications. An appropriate torque-angle characterization can reduce the size of the converter and provide an optimal operation of the machine. It also gives insight about the torque ripple of the machine. Torque-angle curves for various stator currents are obtained for two 7.5 hp transversally laminated anisotropic (TLA) SynRMs. The experimental results are found to be in good agreement with the simulated results obtained from a Finite Element Analysis (FEA) software.
