Electrical Steel Structuring, Insulating and Assembling by means of the Laser technologies


Soft magnetic materials, made from stack of steel sheets separated by insulating layers, are becoming crucial in the various end-user industries and applications based on magnetic components and machines (transformers, sensors, actuators, motors, generators). Experts estimate that the growth rate of soft magnetic materials will improve by 7.8% annually in the coming years!

However, the technology used to manufacture steel sheets causes huge energy losses (called iron losses in addition to copper and mechanical losses) and noise (due to induced stresses and vibrations).

ESSIAL will use laser surface texturizing in order to improve the performance and functionalities of laminated magnetic circuits, while preserving a high mechanical and thermal resistance. In addition, the improved materials will be eco-friendly (no emission of pollutant during their working life); and made of materials that are easy to recycle.

At the end of this four-year project, the ESSIAL consortium aims to:

  • Decrease iron losses due to magnetic reversal processes by 20% (namely the excess magnetic losses).
  • Control and decrease mechanical vibrations and acoustic noise by 20%.
  • Make the deposition/removal of insulating layer easier for sustainable manufacturing process chains.
  • Integrate new laser processes with maximum 10% price increase
  • Implement innovative and unconventional technologies along the European manufacturing value chain.
  • Transfer the ESSIAL technology to European clusters and companies.

Achieving these goals will help Europe reaching the objectives of the energy transition agenda, while strengthening European industrial base. The ESSIAL consortium is composed of research centres and companies that cover the whole value chain of soft magnetic materials, with all necessary resources to carry-out the project. The project includes seven Work-Packages, ranging from manufacturing processes to up-scaling for mass production and dissemination.

ESSIAL Virtual Technical Workshop - Andaltec

ESSIAL International Technical Workshop will take place online on 10 September 2020. This event is organised by ESSIAL's partner Andaltec (Centro Tecnológico del Plástico). This event was initially planned on 26 March 2020 at Andaltec Heaquarters in Martos (Jaén), Spain, but had to be cancelled due to the COVID-19 outbreak. Finally, the workshop will be organised virtually as a webinar

The workshop aims at presenting the project results and engage the stakeholders into personal interactions with the project participants. It is open to researchers, engineers and SMEs that may be interested in such a new technology.

Below, the programme of the workshop:

  • 10:00: Opening - José María Navarro, General Manager at Andaltec
  • 10:15: ESSIAL project presentation and laser welding process - Jesús Castillo, R&D engineer at Andaltec
  • 10:30: Electrical steel manufacturing process and microscopy analysis in ESSIAL project - Jean-Pierre Birat and Camille Pineau, consultants and researchers at IRT-M2P
  • 11:15: Break
  • 11:45: ln-line monitoring techniques and upscaling strategies to optimize the manufacturing time and costs - Anne Henrottin, R&D Engineer at Lasea
  • 12:30: Impact of local surface laser treatment on magnetic properties of grain-oriented silicon iron sheets - Manar Nesser, PhD student at UPJV in collaboration with ESIEE-Amiens
  • 13:15: End of the Webinar


Registration is free of charge. You are just re­quired to send your contact data (company name. number of attendants and e-mail address) to jesus.castillo@andaltec.org. The participants will receive the information to access the Webinar platform upon registration.
