A new published paper in IEEE Transactions on Transportation Electrification  Authors: Mohammad Amirkhani; Ehsan Farmahini Farahani; Mojtaba Mirsalim Abstract: This paper proposes an improved biased-flux motor in which the permanent magnets (PMs) are placed between the stator modules, therefore called intermodular PM (IMPM) motor. The proposed structure has increased the torque density while maintaining a low torque ripple. Moreover, due to the specific placement of PMs, the PMs are extensively protected from demagnetization. The operation principle of the proposed IMPM motor is thoroughly discussed using flux modulation theory and is comparatively analysed with other biased-flux structures. Based on this analysis, a new theoretical formulation is also drawn to calculate the power factor, which involves design related parameters. It has been studied that since the PMs are far from armature winding in the…

A Dual- Stator Machine with Diametrically Magnetized PM: Analytical Air-gap Flux Calculation, Efficiency Optimization and Comparison with Conventional Dual-Stator Machines. . Authors Shahin Asgari, Reza Yazdanpanah, Mojtaba Mirsalim Abstract This paper presents a design and optimization procedure for a dual-stator machine with a diametrically magnetized PM to improve the electromagnetic performance. First, analytical design equations are presented based on MEC analysis; they are used to design a basic dual-stator machine. Then, by applying an artificial intelligence algorithm, the machine is optimized to achieve high efficiency and torque density, and low pulsating torque for direct-drive applications. A quantitative comparison is performed between the optimized new machine and conventional dual-stator machines to evaluate the performances and improvements of the understudy machine. The machine performance, including air-gap flux density distribution, back electromotive force,…
