3D flux configuration cost effective switched reluctance motor with small torque ripple content; design and prototyping

IET Electric Power Applications, Volume 18, Issue 12, Page 1939-1947, December 2024.
Proposing a new 3D flux configuration of reluctance motor which strongly reduces torque ripple and low manufacturing costs has been set and addressed here as the main objective of this study. Abstract Switch reluctance motors (SRMs) have many advantages, such as easy construction, high reliability, low cost, and higher energy efficiency compared to the

A non‐intrusive method for friction and windage losses estimation in induction motors

IET Electric Power Applications, Volume 18, Issue 10, Page 1347-1358, October 2024.
A new technique is proposed to estimate the windage and friction losses in induction motors. This method is completely non‐intrusive and only requires the nameplate data. Abstract In the in‐service induction motors (IMs), friction and windage losses (FWL) value should be determined non‐intrusively. Hence, in the in‐service IMs, instead of measuring FWL,

Robust decomposed system control for an electro‐mechanical linear actuator mechanism under input constraints

International Journal of Robust and Nonlinear Control, Volume 34, Issue 7, Page 4440-4470, 10 May 2024.
Abstract This paper aims to develop a robust decomposed system control (RDSC) strategy under input constraints for an electro‐mechanical linear actuator (EMLA) facing model uncertainty and external disturbances. At first, a state‐space model of a complex multi‐stage gearbox EMLA system, driven by a permanent magnet synchronous motor (PMSM), is ...

Demonstration of a small‐scale power generator using supercritical CO2

Carbon Energy, Volume 6, Issue 4, April 2024.
In response to climate change, the supercritical CO2 (sCO2) power cycle has been studied worldwide and considered the next generation of power generation technology. Most of the study is focused on theoretical analysis, and the experimental investigation of a CO2 power cycle is insufficient. In addition, the power capacity is usually between 0.1 and 10

Action mechanism of axial flow on windage loss in open shaft‐type gap with CO2

Energy Science &Engineering, Volume 12, Issue 3, Page 684-700, March 2024.
The authors of this work investigated the influences of axial flow on windage loss and flow characteristics under the conditions of different axial Reynolds number, rotational Reynolds number and radius ratio to significantly help predict windage loss in open shaft‐type gap of supercritical CO2 turbine‐alternator‐compressor unit.

Influence of the Lubricant Temperature of Splashed Lubricated Worm Gearbox on Churning Power Losses

ITEGAM-JETIA
The 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-
