Abstract :Synchronous Reluctance Motors (SynRMs) have attracted a lot of attention in recent years due to their simple construction, high efficiency and the fact that they do not require rare earth magnets. SynRMs produce torque by directing the magnetic flux through barriers in the rotor, making them a low-cost alternative. The performance of the motor can vary significantly depending on the design of the stator windings and rotor barriers. Different combinations of stator winding types and the number of rotor barriers directly affect the critical performance parameters of the motor such as torque, efficiency, torque ripple, output power, saliency ratio and copper consumption. In this study, SynRMs using six different stator winding types and two different rotor barrier structures (3 and 4 barriers) are analyzed. Output power, efficiency, torque, torque ripple, saliency ratio, d-q axis inductances depending on current phase angle, total losses and copper consumption are investigated. The effect of full pitch and shortened pitch configurations in winding structures on the performance is discussed comparatively. The effect of 3 and 4 barrier rotors on these parameters is also evaluated. These analyses aim to reveal the ways in which winding and rotor configurations in motor design can be used to optimize performance. SynRMs can provide energy efficiency and cost benefits in a variety of industrial applications, therefore selecting the proper configuration is of great importance from both an economic and performance perspective.
