Analysis of Test Results of the Developed Synchronous Reluctance Motor for Public Transport Application

“…Parameter optimal value was found by searching for a maximum value of the magnetic asymmetry that was determined from the impedance of the direct and quadrature axis (ratio 2). High electromagnetic torque will be ensured if the magnetic asymmetry is high (1). In this research, winding leakage impedances were assumed to be equal for both components.…”

“…Simple and reliable construction with lower production costs is SynRM advantage compared to PMSM [1]. PMSMs, especially interior permanent magnet synchronous motors with commonly used high-performance neodymium permanent magnets, have property that demagnetization occurs at a high temperature or by a reverse magnetic field.…”

“…Motors for electrical vehicle application typically are of enclosed type and are characterised by high-temperature rise [2], [3]. SynRM has the potential of equal or higher efficiency compared to IM due to no electrical losses in rotor [1], [4].…”
