In this study, we investigated the effect of the relative position of two stators, with relative angle α, on the machine parameters of flux-modulating hybrid field motors (FHMs). The FHMs are a new type of axial gap motors in which one rotor incorporating iron pieces is sandwiched between two stators, the armature, and the field poles. To consider the magnetic saturation and d-q axis cross-coupling, the machine parameters were calculated using a self-inductance model with current dependencies. From the results of this investigation, we observed the following: 1) Thed-axis flux linkage due to the field poles was the highest when the value of α was maximized. 2) The α has an insignificant effect on the d- and q-axis self-inductances. These findings are useful for future designs of FHMs and their control systems.
