DOI: 10.1109/cefc.2016.7816063
Abstract: A flux-reversal permanent magnet (FRPM) machine typically suffers from unfavorably large cogging torque due to its special doubly salient structure and high air-gap flux density, resulting in undesired torque and speed ripples, as well as… read more here.

DOI: 10.1109/tmag.2021.3072501
Abstract: This article proposes a novel asymmetric-excited flux reversal permanent magnet linear machine (AE-FRPMLM). Different from the conventional FRPMLM with uniform “NS-NS” permanent magnet (PM) sequence, the proposed AE-FRPMLM adopts an asymmetric “NSN-S” PM sequence, which… read more here.
