Investigation of a novel brushless electrically excited synchronous machine with arc-shaped rotor structure

Energy Reports, 2020
Electrically excited synchronous machines (EESMs) with brushes and slip rings are popular in many application fields. Nevertheless, the brushes and slip rings of EESM would increase maintenance cost and reduce the reliability. Addressing this issue, this

Targeting ligament boundaries rather than alignment boundaries in augmented‐reality‐assisted total knee arthroplasty ensures comparable gait patterns between operated and contralateral limbs

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Modern personalised total knee arthroplasty (TKA) techniques aim to mimic natural knee kinematics by focusing on soft‐tissue dynamics rather than static alignment. However, a consistent definition of the optimal ligamentous balance has not yet been established.

Analysis of Cogging Torque Ripple Based on Multiple Square-Wave Radial Superposition MMF for Wound-Field Synchronous Motors

IEEE Access
Bilateral slotting restricts the application of wound-field excitation synchronous motors in underwater vehicles, which focus on vibrations. There are few studies on the wound rotor, and the theory of permanent magnet motors is not entirely applicable ...

Biosurfactant production by Pseudomonas aeruginosa isolated from mining waste: From genomic analysis to development of a polymeric composite for removal of hexavalent chromium

Polymer International, EarlyView.
Biosurfactant was produced by Pseudomonas aeruginosa using andiroba waste from Amazonia. A biosurfactant–alginate composite (Alg/BioS) was successfully synthesized via ionotropic gelation, and achieved up to 70% Cr6+ removal from water. Abstract Environmental contamination by heavy metals represents a significant challenge due to their persistence in ...

Cogging force mitigation techniques in a modular linear permanent magnet motor

IET Electric Power Applications, 2016
Modular linear doubly salient permanent magnet motors are well adapted to linear propulsion systems because of their distinct characteristics, such as high efficiency and power density, reduced maintenance and initial cost, low noise and permanent magnet (PM) leakage flux, and fault tolerance capability.
