Electric vehicles are the future of road transport; the technologies to realise them are being developed now, with new ideas, research, products, and solutions appearing every day. This seminar will give you an idea of some of the latest thinking.
Speakers will discuss dynamic modelling and behavior of electrical steel, measurement for automotive magnets, motors, and charging, optimising e–machines, NVH, manufacturing impacts on EM performance, and more. The seminar wil be a virtual afternoon event, with presentations, discussions, and networking opportunities (UK times).
- Bilquis Mohamodhosen, Dassault Systèmes
- Graeme Finch, NPL
- Jonathan Godbehere, MDL
The programme will consist of talks with Q&A, exhibitors, and networking sessions.
Approximate Start Time: 13:00
Approximate End Time: 18:00
All times GMT
The seminar will be hosted on hopin because it offers an intuitive online conference experience. As well as the talks on the Stage, at any time you can
- visit and talk with exhibitors in the Expo,
- set up small Sessions to talk together,
- search for and Invite delegates you want to speak to through the People list,
- Chat to the whole event, a session or an exhibitor’s booth,
- Ask questions of speakers and the whole event via Chat,
- examine the event Schedule in Reception for any changes,
- try the random delegate connection of Networking (an online version of standing in the queue for coffee and talking to the person behind you).

A new approach for dynamic modelling and dynamic behavior of electrical steels for future energy systems
by Hamed Bahmani of Durham University
Electrification of domestic, industrial and transport systems has been recognized as a promising solution to combat the global climate change and its catastrophic consequences on the planet earth. In this respect, electric motors, transformers and reactors are the key electromagnetic devices for the furtherance of the global clean technology and green energy sectors toward a zero carbon economy. Therefore optimized design of magnetic cores for high efficiency electromagnetic devices becomes more important than ever. This requires all aspects of power loss mechanism of magnetic materials and magnetic cores to be fully understood. This talk aims to provide an overview of energy loss mechanism and dynamic modelling of electrical steels for high frequency applications, e.g. electric motors. The proposed approach is in line with the magnetic hysteresis and phenomenological concepts of rate-dependent and rate-independent energy loss components of ferromagnetic materials under time varying magnetic fields.
Uncertainty Quantification - influence of manufacturing imperfections on electrical machines for automotive application
by Stéphane Clénet of L2EP, Arts et Métiers Institute of Technology
In mass production, fabrication processes of electrical machines are not perfectly repeatable with time, leading to dispersions on the dimensions which are not equal to their nominal values. These dispersions on the dimensions which changes from an electrical machine to another, are uncertain and can have detrimental effects on the behavior of the electrical machine (vibrations, efficiency…). The stochastic approach, which consist in considering model parameters as random variables, provides powerful tools to quantify the effects of uncertainties. In this presentation, we propose to illustrate on an example in automotive how the stochastic approach enables to quantify the effects of the dispersions on the dimensions on the behaviour of an electrical machine, like the rotor eccentricity and the stator core deformation. We show also how this analysis can be applied to improve the process of fabrication in order to limit the effect of these dispersions.
