N2 - In this paper, a stator permanent magnet high-speed electrical machine (SPMEM-IPM) is proposed for the flywheel energy storage system, which is equipped with flux-intensifying permanent magnet to improve the torque density and reduce torque ripple. Firstly, the topology of the SPMEMIPM is introduced, and its operation principle is analyzed. Then, the design process of the machine is presented specifically. Furthermore, to investigate the characteristic and the unique advantages of the SPMEM-IPM, a comprehensive performance analysis is conducted between the SPMEM-IPM and the conventional SPMEM (C-SPMEM) without IPM. Finally, a prototype of the SPMEM-IPM is fabricated for verification. The results indicate the superiority of the SPMEM-IPM in torque performance than the C-SPMEM at the same dimensions.
