A study is conducted to derive an optimal rotor construction in permanent magnet synchronous motor (PMSM). By adopting the proposed sub-magnet scheme, both the reduction of higher space harmonics and the enhancement of damping effects are achieved. Analytical and experimental results show that the more number of sub-magnets produces the less space harmonics and the higher damping effects.
