Force Analysis and Torque Production of the Doubly Salient Parallel Path Magnetic Machine

ABSTRACT An in‐depth mathematical analysis of torque and force production mechanisms is presented in this paper for the Doubly Salient Parallel Path Magnetic Motor (DS‐PPMM). This paper focuses on a comprehensive torque force analysis through analytical modelling and is verified by a detailed finite element analysis (FEA). Electromagnetic force distribution, torque ripple characteristics and the contributions of magnetic salience to overall torque production and performance of the machine are analysed. Tangential and radial components of the force vectors are computed using Maxwell's stress tensor. The results confirm the effectiveness of DS‐PPMM in offering high torque density with low torque ripple.
