“…Though the flux-adjusting level are increased, they suffer from a high cost and extra control circuit. The fluxintensifying motors are usually designed with multilayer flux barriers in [16][17][18][19][20]. Compared with hybrid excited motors and memory motors, the airgap flux of flux-intensifying motors can be varied by the adjustment of the flux leakage state without additional windings.…”

In this paper, a novel variable-leakage-flux interior permanent magnet (VLF-IPM) motor is proposed, which is a kind of mechanical flux-adjusting PM motor. The VLF-IPM motor can obtain the advantages of the IPM motor and overcome the difficulty to adjust PM airgap flux by locating a self-activating device that is introduced in this paper on the rotor. The effect of the flux barriers on the flux leakage circuit is analysed by establishing a rotor parametric model to clarify the influence of flux barriers of the VLF-IPM motor on flux-adjusting performance. Then, the electromagnetic performance of VLF-IPM motors with different volume ratios of cylindrical permanent magnets (CPMs) and rectangular permanent magnets (RPMs) are compared by using the finite element analysis (FEA) method, and the experiment results show that VLF-IPM motor with characteristics of 0 < κ rc < 1 has more advantages comprehensively. Moreover, a multiobjective optimization process is adopted based on sensitivity analysis which can reflect the influences of geometric parameters on the optimization objectives including average torque, torque ripple and cogging torque. Then, the Non-dominated Sorting Genetic Algorithm II(NSGA-II) is utilised to determine the optimal model. Finally, a prototype is manufactured and tested, and the effectiveness of the novel VLF-IPM motor and the self-activating device are verified by the simulation and experiments.

“…In Reference 17, the braking torque is analyzed and maximized to limit barking time based on available voltage. In Reference 18, field weakening ability of flux intensifying surface mounted permanent magnet machines are studied considering material cost and energy consumption. The effect of inset PMs on field weakening through varying PM dimension and armature current are analyzed.…”

Summary Flux intensifying interior permanent magnet synchronous machine (FI‐IPMSM) was designed to improve the characteristic of conventional permanent magnet machine, especially, in field weakening region. Increasing a saliency ratio is the main method to achieve this target which leads to increasing reluctance torque than magnetic torque and so improving the machine performance. In this paper, the characteristics of FI‐IPMSM are investigated. The effect of PM material, PM width, PM thickness, flux barriers width, and iron bridge thickness on the machine parameters is studied. Machine inductances, no‐load and full‐load characteristics are analyzed. A comparison is carried out between the FI‐IPMSM and conventional IPMSM to evaluate the improvement in machine performance. Two‐dimensional time‐steeping finite element method (FEM) is employed in analysis of the FI‐IPMSM and conventional IPMSM.
