Comparative analysis of segmental rotor type switched reluctance motors with single teeth winding

Switched reluctance motor: Research trends and overview

“…8. Flux reversal leads to an increased magnetomotive force (MMF) requirement and core loss, resulting in low electric utilization of the motor [27]. Therefore, structures adopting short flux path can be considered instead to improve performance, as summarized in [28].…”

Comparison of winding configurations in double‐stator switched reluctance machines

“…Moreover, due to its unique two stator construction, the cooling surface of the inner windings is limited. For these reasons, the authors of [11, 12, 17] propose the use of concentrated windings, thereby shortening the end windings and reducing losses. High‐torque density within lower torque operation regions has also been noted; however, a more detailed analysis is needed as core losses and thermal aspects have not been discussed in the previous work.…”

“…However, the unaligned inductance of DSSRMs is hardly affected by saturation, as the fluxes generated by the outer and inner stators are in opposite directions. The stator configuration of the DSSRM provides for a higher copper area, and more importantly, a higher energy conversion ratio is achieved through the flux rerouting given by two‐sided excitation [9–12]. In addition to higher torque density, the double‐stator configuration results in less torque ripple and noise emissions than conventional SRM [8, 13–15].…”

Design and Analysis of a Novel 16/10 Segmented Rotor SRM for 60V Belt-Driven Starter Generator

“…In [11], Mecrow et al propose a novel SRM with full pitch windings to improve the torque density at the expense of the longer end-windings, which is not suitable for short axial length machines. In [12], Z.Y. Xu et al propose a 6/5 segmental rotor type SRM with single teeth winding.…”
