“…Synchronous reluctance machine (SynRM) can be regarded as a potential candidate for alternative of PM machines in EVs/HEVs due to low cost and environmentally friendly. Different from SRMs, rotors of SynRMs are relatively complicated [48], which can be divided as axially laminated (AL) rotor [49], [50] and multi barriers (MB) [51]- [54] rotor, as shown in Fig. . SynRM with AL rotor has higher saliency ratio that can help achieve higher torque density.…”

“…In general, SynRM suffers from drawbacks as complicated rotor structure, non-linear characteristic and high torque ripple. The optimization of machine topology is studied in [50], [51], and the effect of saturation is considered in [52], [53]. The acoustics issue by torque ripple is optimized in [54].…”

The synchronous reluctance machine has gained popularity in traction and other smaller application thanks to its design that need very little or even no permanent magnet. Without internal permanent magnet assistance, an adequate level of torque density could be achieved by having an optimized rotor design to attain the optimum ratio of direct inductance over quadrature inductance. In order to properly control the machine, the direct and quadrature position need to be identified. In this study, a segmented rotor topology without permanent magnet was chosen. We evaluate the direct and quadrature position of the rotor topology, its saturation level and provide the flux linkage and the inductances of the machine.

“…As the key saliency factor of the SynRM will be the inductance difference between its direct-(d-) and quadrature-(q-) axes, many efforts have been focused on the proper controls of the stator currents projected onto these two orthogonal axes to indirectly enhance the torque outputs [3]- [5]. In addition, by following some optimization techniques, the optimal parameter compositions of the SynRMs based on the given machine structures and operational objectives were also formulated in [6]- [8]. Also, to obtain large inductance deviations on the d-and q-axes, some mechanical works must be implemented on the rotor laminated iron cores, and the possible punching effects must also be addressed in system designs and application stages [9], [10].…”

Field Path Design Assessments of a High-Performance Small-Power Synchronous-Reluctance Motor

With the ever rigorous operational efficiency requirements, effective copper loss reduction is one of the viable approaches for smallpower alternative current motors. Among those cost-effective schemes, by eliminating the rotor windings while keeping the same stator structures, the synchronous-reluctance motor (SynRM) offers a potential substitute for those small-power applications that the induction motors are commonly adopted. Since the key factor that affecting the SynRM generated torque will be the difference between its direct-and quadrature-axis inductances, by arranging the rotor field paths aligned to the direct axis and considering the possible cross-coupling magnetic saturations on the rotor ribs and segments, the performance impacts due to field path arrangements on the rotor will be thoroughly evaluated by three-dimensional finite element analyses. From experimental measurements, it is clear that the operational objectives can be achieved and the adequacy of the proposed design guidance can then be confirmed.
