Comparative Study of Dual PM Vernier Machines
World Electric Vehicle Journal, 2021 In this paper, two types of dual permanent magnet (PM) machines, i.e., stator slot dual-PM (SSDPM) machine and split-tooth dual-PM (STDPM) machine, are investigated and compared. Both machines have consequent pole structure with Halbach array PMs.

Torque Converter Operating with Power Splitting Concept [PDF]
International Conference on Aerospace Sciences and Aviation Technology, 2013 Vast researches have been performed to enhance the torque converter due to its significance in different power transmission applications. However, some of its problems are not completely solved. Consequently, this work introduces a principal modification to the torque converter not only to eliminate such problems but also to operate it with advanced ...

Ampere–Oersted field splitting of the nonlinear spin-torque vortex oscillator dynamics
Scientific Reports, 2021 AbstractWe investigate the impact of the DC current-induced Ampère–Oersted field on the dynamics of a vortex based spin-torque nano-oscillator. In this study we compare micromagnetic simulations performed using mumax$$^3$$ 3 and our analytical model based on

Direct Torque Control Schemes for Split-Phase Induction Machine
IEEE Transactions on Industry Applications, 2004 In this paper, DTC (direct torque control) algorithms for split-phase induction machine (SPIM) are established. SPIM has two sets of three-phase stator windings, with a shift of thirty electrical degrees between them. The significant contributions of the present work are: a) two new methods of DTC technique for SPIM are developed.
