Purpose The purpose of this paper is to address a fundamental study and performance analysis of a proposed 6Slots-10Poles permanent magnet flux switching machine (PMFSM) using straight rotor (StR) and 6Slots-8Poles PMFSM with spanned rotor (SpR) structure. Design/methodology/approach Design configuration of the proposed machine was developed using commercial finite element analysis package and JMAG-Designer V.14 software, which provides two-dimensional finite element solver throughout the investigation. An electromagnetic performance analysis is carried out and compared over the two proposed topologies which consist of machines no-load and under-load conditions. Findings This paper demonstrates the finding of the proposed StR structure which consist of more favorable three-phase sinusoidal feature, lower cogging torque and higher output torque. Flux density attributes reveal higher established magnetizing flux concentration in StR compared with SpR. Consequently, the StR structure requires low armature current before it may start to rotate and provides better robust construction with less material consumption and cost. Originality/value This paper describes the novel design of a new PMFSM configuration pertinent for high-speed applications.
