SUMMARY The flux-modulating synchronous machine (FMSM) is a new type of multipole SM with nonoverlapping concentrated armature and field windings on the stator. This paper compares the output characteristics of two FMSMs through finite element analys

This paper presents a new type of multipole synchronous machine (SM) in which 2pa-pole armature and 2pf-pole field windings are centrally wound around individual stator teeth. The proposed machine operates as a (2pa + 2pf)-pole SM by providing a magn

In this paper, the core losses that occur in a 4-kVA flux-modulating synchronous machine (FMSM) were investigated using 2D finite element analysis (FEA), and the results were supported by experiments. A method for reducing the rotor core loss was als

Novel NR2B antagonists with an amide tether were found by an approach to avoid pharmacophoric similarity to dofetilide. Structure–activity relationship investigation led to N-[cis-4-hydroxy-4-(5-hydroxypyridin-2-yl)cyclohexyl]-3-henylpropanamide 14

In this paper, we investigate the Eddy current (EC) losses in the rotors of surface permanent-magnet (PM) synchronous machines, which have concentrated armature windings. By the finite-element method (FEM) analysis, it is clear that the EC losses in

OBJECTIVE AND IMPORTANCE: A solitary fibrous tumor (SFT) is a rare neoplasm of probable mesenchymal origin that was first reported in the pleura but can occur in different sites. Only six cases of SFT arising from the spinal cord have been reported.

In large capacity motor drives, torque ripple evaluation is important in order to prevent problems such as unexpected lifetime reduction caused by mechanical resonance with the load. However, enormous cost and time are necessary to measure torque rip
