Overview of the rectangular wire windings AC electrical machine
CES Transactions on Electrical Machines and Systems, 2019 The rectangular wire winding AC electrical machine has drawn extensive attention due to their high slot fill factor, good heat dissipation, strong rigidity and short end-windings, which can be potential candidates for some traction application so as to ...

Generating arbitrary topological windings of a non-Hermitian band [PDF]
Science, 2020 Topology in the open Controlling the topology of a system provides a route to develop devices that are robust against defects. Whereas earlier developments of topological band theory focused on Hermitian (closed) systems, recent efforts have been toward ...

IEEE Transactions on Transportation Electrification, 2022 The rapidly increasing demand on power density levels of electric vehicle (EV) drive systems is pushing the boundaries of traction motor performance. Hairpin windings are becoming a popular option for EV motors due to their reduced dc losses and improved

Hairpin Windings: An Opportunity for Next-Generation E-Motors in Transportation
IEEE Industrial Electronics Magazine, 2022 Advances in electrical machines and power electronics (PEs) are helping to achieve the power density and efficiency required by the transportation sector. However, the reliability of components and production processes is a challenge.

IEEE transactions on industrial electronics (1982. Print), 2021 Modeling of convection heat-transfer at the end-windings for thermal networks using lumped-parameters has been widely discussed in the literature. Unfortunately, the resulting coefficients are highly influenced by the end-winding shape, the area in the ...

‘Wind, Wind, Wind, Always Winding Am I’: Dickens’s Metafictional Clockwork
The Review of English Studies, 2022 Abstract This article considers the importance of timepieces and clockwork to Dickens’s conception of composition. Whilst the many clocks and watches that saturate his writing have often been read as indicative of an interest in time, the present study considers what the materiality of timepieces—namely, their markets and mechanisms ...

Turn-to-turn fault protection technique for synchronous machines without additional voltage transformers [PDF]
, 2017 This paper presents a novel protection technique for the detection of inter-turn faults in synchronous machines. It is based on the calculation of voltage in the stator windings from the usual phases and neutral voltage, typically available in ...
