Soft Magnetic Materials & Applications


Nov 10th 2020 - Nov 11th 2020

Updated 26 October 2020

Soft Magnetic Materials are an essential area of the overall world of magnetics that we all rely on, but is normally over shadowed by Hard / Permanent Magnetic Materials.

Traditional Soft Magnetic (SMM) alloys such as Electrical Steels and SiFe products have been used for almost a century now and are the ‘back bone’ to most of the transformers in use today. Over the last 20 – 30 years as frequencies have increased to help reduce the size of transformers, more and more exotic products have been introduced into the SMM arena.

This seminar looks to highlight some of the areas associated with SMM, including the complex testing that can be required to validate their performance, as well as introduce some new materials and expand on what can be achieved with these interesting and essential alloys, and provide insight into new developments relating to applications for SMM, with a focus on power electronics from 50Hz up to switching frequencies approaching 1MHz, in the drive to make ever more efficient products that are smaller and cost effective in today’s challenging markets.

Join us to hear a diverse range of speakers including manufactures of components, wound parts, sub-system, and equipment manufacturers during the two afternoon seminar, which will also have networking opportuntirs and panel items.


The programme will run over two days, 10th and 11th November 2020, starting at 13:50 UK each day, through to around 18:00 UK. Each day will consist of talks with Q&A, panel discussions, exhibitors, and networking sessions.

All times are UK.


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).

Advanced Production of Lamination Stacks from High-Saturation Cobalt-Iron Materials
by Dr. Niklas Volbers of VACUUMSCHMELZE GmbH & Co KG

There is an increasing demand for electrical machines with very high power density, especially in the emerging field of electrical flight. If a high power-to-weight ratio is required, cobalt-iron alloys (CoFe) are the best choice among all commercial soft magnetic materials. They offer the highest saturation induction of up to 2.4 T, enabling highest power densities or smallest machine volume and/or weight. CoFe materials are typically being used in strip thickness of 0.20 mm or even down to 0.05 mm, which is much thinner than the standard gauges used for electrical steels. To preserve the superior magnetic properties (regarding both induction and core loss) it is necessary to develop a consistent production route that takes into account the specific material properties. This includes the forming, handling, annealing and stacking of the laminations. The presentation will give an overview of the available high saturation material grades and their properties, including the new high-induction material VACOFLUX® X1 with a reduced Co content of 17%. In addition, different part production routes with their respective advantages and challenges will be discussed. While the prototype production routes offer flexibility in design and short lead times, the serial production routes aim at lower production cost and better scalability. ® registered trademark of VACUUMSCHELZE GmbH & Co.

Effect of passive inverter output motor filters on drive systems
by Dr. Dennis Kampen of BLOCK Transformatoren-Elektronik GmbH

The evaluation shows the effect of different on the market available inverter output filters on important drive system characteristics. Each filter is explained and the filter effect on motor insulation, inverter losses, cable losses, motor losses, audible noise, EMI, bearing currents and costs is compared. This paper offers a comprehensive overview and might help drive system designers in choosing the most suitable passive filter solution.

Validation of metal alloy powder core under pulse condition
by Mr. JC Sun of Bs&T Frankfurt am Main GmbH

Metal alloyed composite with its gradual soft saturation experiences exponential growth in the last decades, validation of such kind of soft magnetic composite is a challenge. Damped oscillation is good alternative to characterize the magnetic properties, in saturation and loss i.e. quality factor.

New high frequency metal magnetic materials developments and future trends
by Dr. Junwu Nie of DMEGC

The third-generation semiconductor substrate materials, such as SiC, are characterized by wide band gap, high thermal conductivity, high saturation electron drift rate and high bonding energy, which meet the requirements of modern electrons for high temperature, high power, high voltage, high frequency and radiation resistance. Chip development drive electronic device materials to follow up with high frequency. Usually in weak current control environment: the requirements of UPS and the purity of electric energy used in precision instruments make filtering necessary. The power factor correction function must be equipped in the circuit with inductor in the load to reduce the phase difference loss. Depending on the protection of multiple induction devices, soft magnetic materials are widely used. The superfine insulating powders of FeSiAl and FeNi are applied to the development of integrated molded inductors, or special-shaped "H" and " П " small inductors, respectively. As well as, the n!stairs need to climb before great breakthrough of technology from powders to devices for current control.

Transformer design for Full-Bridge Phase Shift converter
by Dr. José María Molina, Mr. Lucas Nicieza of Frenetic

High frequency magnetics have become the main bottleneck in the power supply design, in order to increase the power density. The topology Full-Bridge Phase Shift is a wide commonly used in power supplies where galvanic isolation is required for power levels above 200 W. In this presentation, we will discuss some key aspects of the design of this transformer.
