Abstract

This article proposes the permeance and inductance modeling of a new double-stator hybrid-excited flux-switching permanent-magnet (DSHE-FSPM) machine. First, based on the machine design, the DS coupling analysis is presented, which refers to the mutual influence between double stators. In fact, different coupling degree leads to different modeling methods of DS machines, which reduces the workload and increases the modeling efficiency. For DS-FSPM machines, the main affecting factors of the coupling degree are the rotor configuration, PM mutual suppression, and load condition. The specific influences of all the factors are summarized. Second, based on coupling analysis, analytical permeance-magnetomotive-force (MMF) model fit for typical DS-FSPM machines is built up. The effects of hybrid excitation and flux barriers are also taken into consideration. The analytical results accommodate great agreement with simulated counterparts. Third, based on the magnetic field deduction, the inductance model is built, considering leakage inductances. As a result, the analytical inductance well agrees with the simulated and measured counterparts within the calculation error of 5%. Also, the inductance mismatch experiments are carried out with the prototype, which can further verify the modeling of the proposed DSHE-FSPM machine.
