Design and Optimization of a Novel Wound Field Synchronous Machine for Torque Performance Enhancement

Energies, 2018
This paper presents the design and optimization of a novel wound field synchronous machine topology, in which permanent magnets (PMs) are introduced into the rotor slot opening with segment configuration for high quality output torque performance.

Performance estimation of interior permanent-magnet brushless motors using the voltage-driven flux-MMF diagram [PDF]

, 2006
The flux-magnetomotive force (flux-MMF) diagram, or "energy conversion loop," is a powerful tool for computing the parameters of saturated interior permanent-magnet brushless motors, especially when the assumptions underlying classical dq theory are not ...

Fish welfare in a changing world: New developments and current challenges

Journal of Fish Biology, EarlyView.
Abstract The welfare of non‐human animals is central to ethical discussions on animal use, with increasing attention to fish welfare across research, aquaria, aquaculture, and fisheries. This paper reviews current theoretical approaches to animal welfare and recent advances in defining and assessing fish welfare since the seminal paper by Huntingford ...

Old Skool Spinning and Syncing: Memory, Technologies, and Occupational Membership in a DJ Community

Journal of Management Studies, EarlyView.
Abstract We show how technology and its temporal instantiations act as material‐relational mnemonic devices that provide temporal anchors for collective remembering in occupations and form the basis of what we call an 'occupational mnemonic community'.

Improved direct torque control using Kalman filter: application to a doubly-fed machine [PDF]

, 2009
Direct Torque Control (DTC) has been extensively researched and applied during the last two decades. However, it has only first been applied to the Brushless Doubly Fed Reluctance Machine (BDFRM) a few years ago in its basic form inheriting its intrinsic

Performing Micro‐Role Transitions in Open Strategy

Journal of Management Studies, EarlyView.
Abstract Open strategy (OS) requires contributors with a variety of functional backgrounds to episodically perform a strategy role in addition to their functional responsibilities. These actors engage in micro‐role transitions as they temporarily shift from one role to another.

A SyR and IPM machine design methodology assisted by optimization algorithms [PDF]

, 2012
The design optimization of synchronous reluctance (SyR) machine and its extension to internal permanent magnet (IPM) motors for wide speed ranges is considered in this paper by means of a Finite Element Analysis-based multi-objective genetic algorithm ...

Simulation Technique of Synchronous Reluctance Bearingless Machine

Environment. Technology. Resources. Proceedings of the International Scientific and Practical Conference, 2015
Magnetically levitated rotor electric machines can be used under such conditions wherein application of conventional bearings is impossible because of presence of lubrication. Active magnetic bearings application requires rotor length increase and stalling speed is decreased.

Keep on Keepin’ on Down Under: Administrative Heritage and the Strategic Realignment of Multinational Enterprises in Australia During Deglobalization, 1914–79

Journal of Management Studies, EarlyView.
Abstract We analyse the behaviour of multinational enterprises (MNEs) within a host nation – Australia – during deglobalization (1914–79). Deglobalization is often portrayed as a drastic event to which MNEs respond swiftly, probably through withdrawal from host countries.
