TL;DR: An overview of the stator-PM machine is presented, with particular emphasis on concepts, operation principles, machine topologies, electromagnetic performance, and control strategies.

TL;DR: In this paper, the authors investigated the effect of the rotor pole-arc on the phase back EMF waveform of a typical three-phase FSPM motor with 12 stator teeth and ten rotor poles and found that there is a significant difference in the magnetic flux paths associated with the coils of each phase.

TL;DR: The developed field modulation theory not only unifies the principle analysis of a large variety of electrical machines, including conventional dc machine, induction machine, and synchronous machine which are just special cases of the general field modulated machines, thus eliminating the problem of the machine theory fragmentation, but also provides a powerful guidance for inventing new machine topologies.

TL;DR: In this paper, a hybrid excitation flux-switching (HEFS) motor is proposed, in which the airgap field can be easily controlled and is favorable for hybrid vehicles, and the preliminary topology, operation principle, design and static characteristics including phase flux-linkage, back-EMF waveforms under different excitations as well as cogging torque are evaluated based on finite element analysis.

TL;DR: By employing redundant winding in the existing F SPM machine topology, a new redundant FSPM (R-FSPM) machine is proposed for a fault-tolerant operation of critical applications.
