modulation theory, which employs homopolar permanent magnets (PMs) placed between …

Electric machines provide the conversion of mechanical energy to electrical energy (in the
generating mode) and vice versa (in the motoring mode), via magnetic energy storage in …

In this paper, the back-electromotive force (back-EMF) characteristics of the flux-reversal
permanent magnet (FRPM) machines with different magnetization methods and winding …

Flux reversal permanent magnet (FRPM) machine, with magnets mounted on or inserted
into the stator, is favorable for the direct drive applications. In this paper, an FRPM machine …

In this paper, a flux reversal machine (FRM), which has a larger torque density and a
smoother torque waveform than the conventional FRM, is introduced. The FRM has the …

This paper comprehensively studies the electromagnetic performance of flux-reversal
permanent-magnet (FRPM) machines with different consequent-pole PM (CPM) topologies …

In this article, the flux reversal permanent magnet (FRPM) machine with toroidal windings is
presented and analyzed with reference to conventional concentrated windings. First, the …

Harmonics of back electromotive force (back EMF) always have great effects on torque
ripples in flux-reversal permanent magnet (FRPM) machines. In this paper, the back EMF in …

This article proposes a novel topology of consequent-pole switched flux permanent magnet
(SFPM) machine with U-shaped permanent magnets (PMs) for torque improvement, which is …

Cost-effective and high-performance linear motors attract more and more attention for many
applications. This paper proposes a novel double-side linear flux-modulation permanent …
