Nonlinear performance characteristics of 3-phase �ux-switching permanent magnet motors (FSPM) are overviewed. ese machines show advantages of a robust rotor structure and a high energy density. Research on the FSPM is predominated by topics such as modeling and machine comparison, with little emphasis given on its performance and limits. Performance characteristics include phase �ux linkage, phase tor�ue, and phase inductance. In the paper, this analysis is done by a crosscorrelation of rotor position and armature current. Due to the high amount of processed data, which cannot be handled analytically within an acceptable time period, a multistatic 2D �nite element model (FEM) is used. For generalization, the most commonly discussed FSPM topology, 12/10 FSPM, is chosen. Limitations on the motor performance due to the saturation are discussed on each characteristic. Additionally, a focused overview is given on energy conversion loops and dq-axes identi�cation for the FSPM.
