Abstract

The flux-weakening potential of a three-phase double-stator (DS) permanent magnet (PM) machine is analysed and presented in this study. Furthermore, the winding inductances of the investigated machine are also presented with reference to their different rotor topologies. The analysis shows that the 12-slot/14-pole machine having alternate-pole wound topology has the unrivalled flux-weakening capability amongst the compared machine configurations. Moreover, the 12-slot/10-pole machine having alternate-pole windings has the greatest fault-tolerant ability, as it exhibits the highest and lowest amount of self-inductance and mutual inductance, respectively. MAXWELL-ANSYS FEA software is employed in the whole predictions. Essentially, the developed double-stator permanent magnet machine in this study is analysed with a particular interest on its inductance characteristics as well as its torque–speed and power–speed aptitudes, i.e., flux-weakening abilities.
