Novel analysis and design methodology using the newly adopted synthetic flux linkage for interior permanent-magnet (PM) synchronous motors (IPMSMs) with a multilayered PM have been proposed. In addition, cross magnetization between the d and q axes in the IPMSM is taken into account via the proposed synthetic flux linkage, which can be identified numerically and experimentally. It is validated with the experimental ones for the purposely built prototype, and its further effectiveness on control application is introduced.
