IET Electric Power Applications, Volume 19, Issue 1, January/December 2025.Elevated operating temperatures in permanent magnet synchronous motors (PMSMs) induce performance degradation due to partial demagnetization of the permanent magnets and accelerated aging of the insulation system. Effective thermal management is, therefore, critical for ensuring optimal motor performance and longevity.

Assessment of Parameter Estimation Methods for Nonintrusive Loss Estimation of Induction Motors
IET Electric Power Applications, Volume 19, Issue 1, January/December 2025.Nine methods for induction motor equivalent circuit parameter estimation from catalogue data for on‐site loss estimation are assessed. The combination of high accuracy and total absence of nonphysical results is not found in any of the tested methods. The case study of loss estimation with tested motors shows that good accuracy is achievable as long as

Innovative Blade‐Structured Rotor Design for Enhanced Self‐Cooling in Permanent Magnet Machines
IET Electric Power Applications, Volume 19, Issue 1, January/December 2025.This paper proposes a novel self‐cooling solution for surface‐mounted permanent magnet machines using a blade‐structured rotor that draws cooling air through the machine during operation. The design effectively removes heat from critical components, such as end‐windings and magnets, without additional fans or wafters.

Influence of the Lubricant Temperature of Splashed Lubricated Worm Gearbox on Churning Power Losses
ITEGAM-JETIAThe primary goal of lubricating a worm gearbox is to encourage sliding between teeth, which lowers the coefficient of friction and regulates the temperature rise brought on by rolling and sliding friction. Due to both non-load-dependent and load-

Forced Air‐Cooling of Modular Flux Switching PM Machines Using Flux Gaps as Cooling Channels
IET Electric Power Applications, Volume 19, Issue 1, January/December 2025.This paper investigates the thermal performance of modular flux‐switching permanent magnet (FSPM) machines under forced air cooling, highlighting the role of flux gaps between segmented stator cores as additional cooling channels. 3D CFD simulations and experiments show that a 4‐mm flux gap achieves optimal cooling under constant pressure loss, whereas

IET Energy Systems Integration, Volume 7, Issue 1, January/December 2025.ABSTRACT The virtual synchronous generator (VSG) concept is implemented to mimic the properties of synchronous generators and therefore improve the stability of modern power systems. Superconducting magnetic energy storage (SMES) is able to rapidly absorb power in the case of a fault and becomes completely charged due to capacity constraints.
