Technical consultants Ryan is an award-winning engineer and business leader with more than 20 years’ experience in the High-Performance, Heavy-Duty and Off-Highway Automotive markets. Prominent in the development of Power Electronics, Electric Motors and Drives (PEMD) for these demanding applications, he has successfully founded, scaled and exited three businesses in the electric vehicle space. He is currently CEO of eTech49 Limited, an advisory business specialising in disruptive hardware technology in PEMD. In addition, he is Chairman of EV North, an industry group representing the booming EV industry in the north of England, a board member of the North East LEP and an adviser to a number of corporations. Danson Joseph has had a varied career in the electrical power industry, having worked in areas ranging from systems engineering of photovoltaic power plants to developing the battery packs for Jaguar Land Rover’s I-Pace SUV. With a PhD in electrical machines from the University of Witwatersrand in South Africa, Danson has focused on developing battery systems for automotive use. After completing the I-Pace project he formed Danecca, a battery development company with a focus on prototyping and small-scale production work, as well as testing and verifying cells and packs destined for mass production. Dr Nabeel Shirazee graduated from Leicester University in 1990, where he studied electrical and electronic engineering. An MSc in magnetic engineering followed at Cardiff University, where he continued his studies, earning a PhD and developing a permanent magnetic lifting system that has been patented by the university. His interest in magnetics led to a patented magnetic levitation system that was awarded the World’s No 1 Invention prize at INPEX in the USA. In 1999, he founded Electronica, a magnetics research and design consultancy. Since then, he has been involved in various projects, including the design of an actuator motor for a British aerospace company. He has also licensed the levitation technology in France. Ryan Maughan Danson Joseph Dr Nabeel Shirazee Less neodymium, more cerium Engineers at the Korea Institute of Materials Science have developed a process for producing high- performance and cost-effective magnets for high-speed electric motors using cerium to reduce the amount of neodymium (writes Nick Flaherty). Cerium is an abundant rare earth element, while neodymium is in increasingly short supply, driving up prices. The process can reduce the amount of neodymium required by 30% while increasing the coercivity and remanence of the magnets. The magnetic performance of the magnets is sufficient to replace N42M-graded commercial magnets. The shortage of neodymium is being driven by the demand for anisotropic neodymium iron boron (Nd-Fe-B) permanent magnets for high-efficiency motors in hybrid/ electric vehicles. While cerium is abundant, the intrinsic magnetic properties of the Ce 2 Fe 14 B used in magnets are much lower than those of Nd 2 Fe 14 B. The hot-deformation process is well-known for fabricating high- performance Nd-Fe-B magnets comprising ultra-fine grains. This was used to create magnets with a high cerium content that had a far higher remanence than those produced by sintering. MOTOR MAGNETS Autumn 2022 | E-Mobility Engineering 11 TheGrid
