SUMMARY This paper describes the N − T characteristics of magnetic gear motors in which permanent magnets are used only in the high‐speed rotor. The N − T characteristics for the cases with and without high‐speed rotor slip are computed by finite element analysis under vector control. These characteristics are verified by measurements on a prototype. Finally, the differences between the computed and measured N − T characteristics are discussed.
