Spaces are limited

Early Registration Discount ends 29 March

Electric Machines are at the very forefront of magnetic related engineering and development. One of our goals is to compliment the fantastic work that already takes place in promoting Electric Machines while fulfilling our responsibility to disseminate the latest technical information to the magnetics community.

Starting with LARM2024 we aim to provide a yearly conference to share developments in all magnetic aspects of Linear And Rotating Electric Machines. This includes soft magnetics, hard magnetics, and permanent magnet free electric machine topologies, for rotating and linear motors and generators.

We want to build on the fantastic success of MMA23 (Magnetic Materials and Applications) event in Hanau this year by bringing this regular 2 day Electric Machines event to life!

Already the event space for LARM2024 is confirmed – we couldn’t be happier that the AMRC have agreed to host the event – and half the speaking slots are already full. If you want to be a part of this event, either to Attend or to Talk then register and get in touch to discuss.

We are also looking to provide exhibitors with great value for money and 8 exhibition spaces are available at a fraction of the cost of many purely commercial events. These events bring engineering staff directly into contact with each other and it’s a great space to have significant commercial conversations. For more details get in touch.


The event will run from 09:00-17:00 (UK time) over two days and will include talks and a tour of the AMRC.


The UK’s Advanced Manufacturing Research Centre (AMRC) is one of several connected centres helping UK industry develop new knowledge, innovations, and technologies to manufacture things better, faster, cheaper and greener. Its research helps aerospace, automotive, space, medical and other sectors manufacturing companies compete on the world stage.

Lightweight motors for electric flight - the magnetically geared advantage
by Dave Powell of Magnomatics Limited

Magnomatics have been pioneering the development of magnetically geared motors since 2006, delivering compact and efficient solutions to the marine, renewables and aerospace industries. The race to zero demands step changes in motor and drive power densities as well as system efficiency improvements, where efficiency is often traded with mass for a specific aircraft. This presentation discusses the development of high torque density and high efficiency magnetically geared motors for aircraft propulsion.

Linear to Rotary Magnetic Gear
by Suleiman Sharkh of University of Southampton

The presentation introduces a permanent magnet linear-to-rotary magnetic gear whose topology is derived based on the operating principle of a transverse flux VRPM machine. It is shown that when the number of poles per unit length on all three members, rotor, translator and stationary flux modulating ferromagnetic pieces, are the same, the proposed gear is essentially similar to a magnetic screw gear with discretised helical magnets. Using different number of poles and iron pieces per unit length provides alternative means for adjusting the gear ratio. The paper describes the design and construction of a demonstrator gear whose dimensions were optimised using finite element analysis. Performance results obtained from finite element analysis and experiment are presented and discussed.

A novel axial flux machine topology for low-voltage traction applications
by Chris Lines of Saietta Group Plc

Saietta has developed a patented yokeless dual-rotor axial-flux machine topology with distributed windings that is particularly suited to low voltage traction applications. The unique arrangement offers performance and efficiency benefits given the highly sinusoidal airgap flux density distribution. Also, the cooling of the stator windings is effective owing to the high number of slots per pole and a good radial heat path to a simple circumferential-flow water jacket. The high number of slots per pole also aids in the machine exhibiting a very low cogging torque. The motor has been designed for cost effective manufacture in high volumes and is fully sealed from the environment. Discrete grain-oriented electric steel lamination stacks are used as the teeth for the yokeless stator and the formed windings are produced from standard round copper wire. Crucially, the stator does not rely on either the windings or a stator core to provide its final structure, but rather a novel overmoulding process has been developed to fully encapsulate the stator. Lastly, simple (unsegmented) magnets and solid rotor back irons can be used without significant efficiency penalty, which brings further cost benefits.

Linear Generators for Wave Energy
by Nick Baker of Newcastle University

Offshore wind is now well established with GW of installed capacity. Wave energy is an alternative form of marine energy which also has the potential to contribute to sustainable electricity generation. This comparatively immature technology operates at linear speeds at least an order of magnitude lower than that found in other sectors, posing unique challenges to the electrical power train.

Magnetic properties and applications of Non-Oriented-Grain (NO) FeSi alloys: trends and perspectives
by Enzo Ferrara of INRIM, Istituto Nazionale di Ricerca Metrologica, Turin (Italy)

Patented by Robert Hadfield at the beginning of the XX century, since from their introduction as the first commercial alloys used in electrotechnics, NO FeSi steels, thanks to their low-cost composition and basic production processes, dominate the global market of soft magnetic materials. NO FeSi acted as a test bench to recognize relationships between, composition, structure, and magnetic performance. Their structural, mechanical, and magnetic properties have been so far matter of investigation, providing knowledge on the role played by e.g. grains size and boundary, cube crystallographic orientation, electrical resistivity, thickness, and mechanical stresses on magnetization processes and soft magnetic features in the low to medium frequency range. Actually, while thinner laminations are available for applications at higher frequencies and green guidelines pursue recycling and renewable resources, improvement and simplification of NO magnetic steels production processes remain a key issue to meet sustainable transformation and use of electrical energy.

Screen printing electrical steel sheets – possibilities and advantages
by Torsten Mix of Fraunhofer Institute for Manufacturing Technology and Advanced Materials, Germany

High power densities and efficiencies are crucial for electrical machines. Especially for high frequency motor application with innovative designs they require the right type of electrical steel sheet. Additive manufacturing offers the possibility of printing sheets with lowest losses, as thinner sheets and different alloy contents can be produced. The additive manufacturing of Fe-6.5Si and other Fe-based electrical steel sheets by screen printing illustrate new possibilities for producing mechanical robust sheets with low losses in desired end geometry.
