| This paper investigates the inductance characteristics of a novel 3-phase (12-stator-tooth/10-rotor-pole) flux-switching permanent magnet (FSPM) machine with doubly-salient structure based on finite element analysis (FEA). Firstly, the topology and operation principle of the FSPM machine are introduced. Secondly, the apparent and incremental inductances are defined. Then, the conventional calculation method of transforming the inductance in stator frame into rotor frame is performed. To overcome the shortcoming of the conventional method, e.g. time-consuming, a new simplified and fast method is proposed to obtain the d-axis and q-axis inductances directly and accurately at two special rotor positions. The proposed method is validated by the comparison of the predicted results by two ways. |
