Abstract: This paper deals with a 16-pole, 18-slot fractional-slot concentrated-winding permanent-magnet synchronous machine (PMSM) for articulated robot applications considering several multiphysics analyses. Optimized PMSMs are compared analytically and experimentally considering electrical and mechanical aspects. The electrical and mechanical analysis results are well matched with the experimental results in terms of the efficiency and temperature. The design, analysis and experiment with the PMSM for articulated robot applications were performed successfully.
