Torque Quality Improvement of an Open-End Winding PMSM [PDF]
2018 IEEE Energy Conversion Congress and Exposition (ECCE), 2018 This paper proposes a new closed-loop control strategy which improves the quality of the torque output of an open-end winding (OEW) permanent magnet synchronous motor (PMSM) with common DC bus. Such a configuration provides a path for the zero sequence currents (ZSC) to flow in the windings.

An Open-End Winding Four-Level Five-Phase Drive [PDF]
IEEE Transactions on Industrial Electronics, 2016 A four-level five-phase open-end winding (OeW) drive topology is introduced in this paper. The drive comprises a five-phase induction machine with open-end stator windings, supplied using two two-level voltage-source inverters with isolated and unequal dc-link voltages, in the ratio 2 : 1.

Supersymmetry breaking, open strings and M-theory [PDF]
, 1998 We study supersymmetry breaking by Scherk-Schwarz compactifications in type I string theory. While in the gravitational sector all mass splittings are proportional to a (large) compactification radius, supersymmetry remains unbroken for the massless ...
