Permanent Magnet Synchronous Generator Stability Analysis and Control
Procedia Computer Science, 2016 AbstractIn this paper a theoretical approach has been developed to address the stability problem of permanent magnet synchronous generator (PMSG). It is used because of great advantages such as reliability and effectiveness. The proposed technique is obtained through three stages. First stage is to apply linear approximation to the original system. The

Optimization of Magnetic Milli‐Spinner for Robotic Endovascular Intervention
Advanced Robotics Research, EarlyView.This work presents the design optimization of a multifunctional magnetic milli‐spinner for high‐speed propulsion and efficient clot debulking. The optimized design achieves an ultrafast swimming velocity of 55 cm/s (≈175 body lengths/s) in saline water, enabling stable upstream swimming against strong physiological flows and establishing magnetic milli‐

Advanced Science, EarlyView.In this work, ultrafast laser‐induced spin transfer and spin relaxation dynamics in 2D van der Waals antiferromagnetic CrI3/CrGeTe3 heterostructures are investigated. Laser excitation is demonstrated to induce pronounced interlayer nonequilibrium spin dynamics and ultrafast magnetic moment reconstruction, driving a transition from an antiferromagnetic (

Prediction of the Inductance in a Synchronous Linear Permanent Magnet Generator
Journal of Electromagnetic Analysis and Applications, 2011 This paper presents calculations of the varying inductances profile for a synchronous linear surface mounted permanent magnet generator in an ABC reference system. Calculations are performed by utilizing the reluctance term, known from analytic calculations and finite element method simulations.

Advanced Science, EarlyView.Photonic time crystals (PTCs) are systems in which electromagnetic parameters are modulated periodically in time, producing momentum bandgaps via temporal scattering rather than spatial Bragg processes. This review examines the theoretical frameworks, modeling, and computational tools for time‐varying media, and summarizes experimental demonstrations ...

ADVANTAGES OF PERMANENT MAGNET SYNCHRONOUS GENERATORS
Today, no one will be surprised by the fact that many relays and sensors, rotors of motors and generators, even in such grandiose structures as industrial hydroelectric power plants and wind turbines, use neodymium magnets in their units instead of the excitation windings that are becoming a thing of the past.
