Condition monitoring of permanent magnet AC machines for all‐electric transportation systems: State of the art

open access: yesIET Energy Systems Integration, Volume 6, Issue 3, Page 213-229, September 2024.
Abstract The current state of the art on emerging and efficient techniques for condition monitoring of permanent magnet (PM) alternating‐current (AC) machines deployed in electric vehicle (EV) applications is presented. The discussion includes the most common and specific types of faults in PM motors, such as rotor demagnetisation and stator inter‐turn

Analysis of hybrid AC/DC transmission system: A Turkey case study

open access: yesIET Generation, Transmission &Distribution, Volume 18, Issue 18, Page 3017-3028, September 2024.
This study aims to increase the transmission capacity without experiencing right‐of‐way problems by converting Turkey's existing high voltage AC systems to hybrid AC/DC systems. With such a design, the variation of the electric and magnetic fields that will occur has also been analysed by 2D modelling in FEMM4.2.
