The flux-modulating synchronous machine (FMSM) is a new type of multipole SM with nonoverlapping concentrated armature and field windings on the stator. This paper compares output characteristics of two FMSMs through finite-element analysis (FEA) and experiments. In both the FMSMs, attachment positions of the armature and field windings are swapped. To determine the reason for discrepancies in their output characteristics, unsaturated inductances were calculated using a d-q equivalent circuit. In addition, the calculated results of the inductances were confirmed by visualization of leakage fluxes using the FEA. The results of the study show that the synchronous inductance can be reduced by attaching the armature winding to the air-gap side of the stator teeth and that its reduction leads to an increase in output power.
