State-of-the-Art Technology for Innovative Electric Motors


Electric motor is one of the few inventions that shaped electrical technology the most. The very beginning of the electric motor is found exactly two hundred years ago, in 1821. However, over the time many significant changes in the technology have been moving forward, opening new frontiers for innovative electric motors. In particular, new trends in e-mobility as the developments of EV (Electric Vehicles) and HEV (Hybrid Electric Vehicles), forced new requirements related to size/weight of the drive and resulted in awesome innovations for in-wheel electric motors, thus creating substantial solutions.

The first question to be answered is “What makes an electric motor innovative?” First, it is an innovative design topology and use of novel materials, then an innovative production technology and, the most recently, new state-of-the-art manufacturing processes. A design engineer of electric motors is seeking for answers to the following: (i) What are structural/shape choices that define novel motor topology and make the motor better-performing? (ii) What are the most effective novel materials for obtaining the best of each component/shape in the design layout? (iii) How to extend the limits of the motor’s performance reached today? (iv) What are novelties in the electric motor design? (v) How is an innovative motor manufactured?

Another important aspect to discuss is certainly the state-of-the-art production technology. The most recent 3D printing technology developments, have added a huge value to the designing, prototyping as well as manufacturing processes. The broad spectrum of production applications has been unlocked. The significant reduction of time and money consumption, required for the stage of prototyping, led to cost-effective massive motor production. The laser technology is growing, becoming more workable and affordable, such that additive manufacturing (AM) from 3D printing of only parts of an electric motor has been moved to the printing even the whole motor structure. Using 3D computer aided design (CAD), and having in hand 3D scanners, additive manufacturing allows the creation of objects with precise geometrical shapes, built layer by layer with adding multi-material, opposite to classical manufacturing when the excess of material is subtracting.

The AM technology is broadly divided in three types: (i) sintering whereby the material is heated without being liquified to create complex high resolution objects; (ii) melting where metal powders are melted so that the particles stick together and shaped; (iii) stereolithography, which uses the process of photopolymerisation, to create torque-resistant ceramic parts. In the talk few selected processes are discussed and elaborated: Fuse Deposited Material (FDM), Selective Laser Sintering/Melting (SLS/M), StereoLitography Apparatus (SLA).

To present days several pioneering research centres throughout the world have reported successful applications. At the end of this talk, more interesting applications are presented. It is started with the earliest practical implementation of 3D printing for the purpose of electric motor prototyping in e-mobility, where only some parts of the motor topology have been manufactured. However, the real challenge for electric motor designers is producing the whole motor by using AM, the task still rather complicated. The first fully 3D-printed stator, developed by an enthusiastic group of electrical engineers from Chemnitz University, Germany and premiered in 2018 at ‘Hannover Messe’ – the trade fair, will be presented and explained.

Kit Oung, PhD

I am an energy and resource efficiency strategist, consultant and trainer. I help businesses, both commercial and industrial companies across five continents, maximise their energy and resource efficiency; identify the minimum investment cost pathways; and reduce the often complex and technical messages in to a clear, meaningful and simple-to-understand business case.

Having worn many hats in my 24-year career – design, technical operations, management, consultancy, equipment supplier, energy performance contracting, training, and in policy development – I have a unique ability to understand technical and managerial challenges, work with different stakeholders, manage multi-disciplinary projects, identify opportunities for improvements, and troubleshoot performance deficits. My work helps managers to engage with senior executives, disarm barriers for performance improvement, and bring about its implementation in a safe and healthy manner.

I also train new and aspiring professionals, and in-company energy and resource efficiency champions in ISO 14001 environment management system, ISO 45001 occupational health and safety management system, ISO 50001 energy management system, integrated management systems, ESOS lead assessor qualification, at British Standards Institution (BSI), and Institution of Chemical Engineers (IChemE).


I volunteer in IChemE’s Congress, IChemE’s Energy Community of Practice, IChemE’s annual sustainability awards judging panel, UNIDO’s global energy management leadership awards judging panel, and take part in developing Nationa, Regional and International standards. I chaired ISO 14002-2 (current), ISO 50002 (current), PAS51215, EN16247-3, and participated in the development of ISO 14001 series, ISO 50001 series, and EN16247 series of standards.
Complete CV





The main aim of this presentation is to give an overview of the current state of play for energy and resource efficiency and the things that scientists and engineers can do to reduce energy and resource consumption, use them responsibly, minimise their environmental impact, and avoid irreversible climate change.

It covers the current understanding of why the application of energy and resource efficiency is much slower in real corporations than the available technologies and know-how. This is used to identify the broad actions that needed to be addressed in order to adopt and accelerate energy and resource efficiency.

Moreover, the presentation gives an overview of the life cycle of a corporation – its products and services – ranging from concept, design, through to the end of life, and highlights the actions scientists and engineers contribute at each of the life cycle stages.

Finally, the presentation rally participants to think about and declare the actions they will take to accelerate energy and resource efficiency.
