A new type of Dual Stator Permanent Magnet (DSPM) machine, which is capable of producing high torque at low operating speed, for direct-drive applications is proposed and analyzed in this study. ANSYS-MAXWELL-2D/3D computational software is employed in the prediction of the machine performances, using the finite element technique. The considered machine performance indices are flux linkage, Electromotive Force (EMF), inductances, torque, losses, and efficiency. It is found that the proposed machine has better output torque performance than its single stator equivalent; though, with attendant higher cost and manufacturing complexity. More so, the proposed machine has sinusoidal and symmetrical flux linkage and electromotive force waveforms. These qualities are desirable for smooth control operations of brushless Alternating Current (AC) machines; and direct-drive uses. Further, the impact of design parameters on the performance of the proposed DSPM machine is also considered in this work. The investigated geometric design variables include the: split ratio (So), Permanent Magnet (PM) size, rotor radial thickness (Rt), stator tooth thickness (Wt), rotor inner iron-width/pitch ratio (Riw), and rotor outer iron-width/pitch ratio (Row), etc. The overall machine model is obtained using the intrinsic evolutionary optimization algorithm of the adopted software.
