Permanent magnet (PM) brushless machines having magnets and windings in stator (the so-
called stator-PM machines) have attracted more and more attention in the past decade due …

Permanent magnet (PM) machines inevitably suffer from cogging force, which does not
contribute to the average output torque (force) but contributes as a type of torque (force) …

Permanent-magnet vernier (PMV) machines are attracting more and more attention due to
their high torque density and simple mechanical structure. In this paper, a novel PMV …

Brushless stator-mounted traction motors, which are new and emerging, have many
potential applications in the electrified transport industry. Brushless stator-mounted …

This paper proposes a consequent-pole flux reversal machine (CP-FRM) with biased flux
modulation theory, which employs homopolar permanent magnets (PMs) placed between …

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

A novel hybrid excitation flux reversal machine (HEFRM) is developed for application in
electric vehicle propulsion. The proposed machine has a simple reluctance rotor and a …

This paper proposes several slot-pole combinations of flux-reversal machines (FRMs) with
fractional-slot windings (FSWs) to achieve a larger torque density and a lower pulsating …

Magnet segmentation is an effective and simple technique for cogging torque reduction in
high power permanent-magnet (PM) synchronous machines; however, it deteriorates air gap …

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 …
