“…It can be found that the two machines share a common elaborate stator of twelve poles with embedded rectangular PMs and concentrated coils, with each possesses a robust and passive rotor of 10 and 14 poles respectively. The operation principle and general design guideline of such PMFS machines can be found in [2], while the detailed design and performance analysis of the proposed machine have been reported in [32]. The key design parameters of the PMFS machine, on which the torque ripple reduction and analysis in this study are based, are given in Table I. The PMFS machines, which inherently use unique doubly salient structure, still suffer from the inevitable torque ripple.…”

This paper investigates the torque characteristics of permanent magnet flux switching (PMFS) machines with rotor step skewing. The cogging torque, torque ripple and average output torque of a PMFS machine with a common stator and different rotor pole widths and rotor pole numbers are first established using two-dimensional (2-D) finite element analysis (FEA). A cost-effective rotor step skewing technique is then proposed to reduce the cogging torque and torque ripple of the machine with two different rotors. The results have revealed that the least step number and angle for optimal torque ripple mitigation of the PMFS machine are determined by the harmonic contents of the torque pulsation and the rotor pole number. The influences of load conditions on the machine torque characteristics are carried out by varying current excitations. The corresponding three-dimensional (3-D) FEA models are constructed and experimental prototypes are built for validations.

Permanent magnet flux switching machines (FSPMs) have attracted considerable attention in recent years, due to their outstanding characteristics to operate as brushless AC drives. Since they are relatively new, there are particular challenges not only for their design procedure but also for their operating principle comprehension. This study highlights several issues on FSPMs from the basic operation description to their key design points. After a comprehensive description of FSPMs working principles, a detailed discussion is presented on their armature winding design. In addition, this study reviews various methods for their performance modification, including torque profile, electromotive force, and loss characteristics. This study also surveys field regulation technologies, modelling and design optimisation methods applied to FSPMs along with their fabrication and cost issues.

“…Meanwhile, it also enables the stators of FSPM motors very suitable for modular production. In addition, owing to the fact that the flux due to magnets are magnetically in parallel with that from the armature windings, the magnets can withstand demagnetization which is required in flux-weakening operation [9], [10]. However, this may cause cooling problems since the PMs are surrounded by armature coils which contain the main heat source.…”

Published researches on flux-switching permanent magnet (FSPM) motors are focused on the analysis methods of electromagnetic performance, optimization design of lamination dimensions, combinations of stator slots and rotor poles, different kinds of field-excitations, and mechanical stability, etc. However, the manufacturing considerations for mass productions and their influences on the electromagnetic performances of FSPM motors, especially for the applications of electric vehicles (EVs) and hybrid electric vehicles (HEVs), have not been covered in previous works, which instead, are the main contributions of this paper. The complex stator structure of FSPM motors give challenges not only on mass production, but also on the cooling systems, since the permanent magnets (PMs) are surrounded by concentrated armature coils which contain the main heat source. Hence, the modular manufacturing methods are proposed and investigated. Then, a water-cooling system and the idea of an improved real time control scheme taking into account temperature variations are proposed and implemented. Moreover, inaccurate concentricity problems and unbalanced radial forces on rotor are also introduced considering the EVs/HEVs applications.
