Hub Director Presents for the IET

19 April 2023

On 18 April 2023, FEMM Hub Director Professor Geraint Jewell presented to members of the IET’s South Yorkshire Division in the Diamond Building, University of Sheffield.

His presentation titled ‘Electrical machines: Application and manufacture’ was followed by a question and answer session. The abstract for the presentation can be found below.

Future electrical machines: Applications and manufactureOn Tuesday 18 April at 6pm GMT, Professor Geraint Jewell will present on ‘Future electrical machines: Application and Manufacture’.Hybrid event which can be attended in person at the Diamond Building, the University of Sheffield, or through use of Microsoft Teams.


Electrical machines are at the heart of the accelerating trend towards the electrification of many industrial sectors, particularly transport. To address emerging requirements and meet the increasing demands of new applications, new electrical machines with improved performance in terms of higher power density, higher efficiency, lower weight and improved reliability continue to be developed. 

As designers push up against material limits, manufacturing technologies become one of the key enablers of improved performance, particularly in the high added value sectors such as aerospace, offshore wind, premium automotive and industrial machinery. Professor Geraint Jewell will discuss these manufacturing challenges and the work being performed to assist UK industry to overcome these challenges and maintain a leading position in the global supply chain for high value electrical machines.

Information on the speaker 

Professor Geraint Jewell is Professor of Electrical Engineering at the University of Sheffield. He is a graduate of Sheffield (BEng 1988; PhD 1992) and has been a member of the academic staff in the Department of Electronic and Electrical Engineering in Sheffield since 1994. 

He held an EPSRC Advanced Research Fellowship (2000-2005) and a Royal Society Industry Fellowship at Rolls-Royce (2006-2008). He has been Director of the Rolls-Royce University Technology Centre in Advanced Electrical Machines since 2006. 

Alongside his academic roles within the department, he served as the Faculty of Engineering’s first Director of Research and Innovation from 2008-2011 and was Head of the Department from 2013-2019. He is currently the Interim Head of the Advanced Manufacturing Group which includes the Advanced Manufacturing Research Centre (AMRC) and its Nuclear counterpart (NAMRC). 

His research interests cover many aspects of electromechanical devices including electrical machines (permanent magnet, switched reluctance, synchronous reluctance) and linear actuators. Much of this research in recent years has been directed towards aero-engine applications in collaboration with Rolls-Royce. 

This research has included high temperature devices (many around 400°C but with one up to 800°C) and several demonstrator starter- generators for aero-engines. He has supervised some 25 PhD students to completion across a wide range of electromagnetic and electro-mechanical topics. 

He currently leads the EPSRC’s Future Electrical Machines Manufacturing Hub. The Hub’s vision is to put UK manufacturing at the forefront of the electrification revolution. The Hub will address key manufacturing challenges in the production of high integrity and high value electrical machines for the aerospace, energy, high value automotive and premium consumer sectors.
