Asymmetrical dual three-phase interior permanent magnet synchronous motors (ADTP-IPMSM) exhibit high torque density and low torque ripple advantages but are associated with complex dynamics that include nonlinear magnetic saturation, spatial harmonics, and mutual cross-coupling between the two stator windings. This paper focuses on simple nonlinear modeling techniques based on stator flux linkage data to simulate the dynamics and electromagnetic torque of ADTP PMSMs. The developed modeling approach has been validated with results from a finite element analysis. The superiority of the nonlinear models over conventional linear models is presented in the paper.
