Abstract

Electromagnetic and electromechanical significances of stator teeth thickness on electric machine outputs are presented in this study. The studied machine is a dual-stator (DS) flux-switching permanent magnet (FSPM) machine. Maxwell-2D finite element analysis is implemented. The investigated machine metrics include: flux linkage, induced-voltage, power, inductance, torque and magnetic force. The compared machine types having equal and unequal stator teeth thickness have its merits and demerits. Generated largest voltage and torque of the equal stator-toothed machine type at rated conditions is 4.75 V and 2.48 Nm, respectively. The developed machine type having unequal stator tooth thickness has matching voltage and torque value of 4.84 V and 2.54 Nm, respectively. Nevertheless, the developed machine type has lower flux-weakening capability, owing to its slightly lower speed range compared to the equivalent machine that has equal stator tooth structure.
