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


ESSIAL is using surface texturing to improve the performance and functionalities of laminated magnetic circuits while maintaining high mechanical and thermal resistance. In addition, the improved materials are eco-friendly (no pollutants emitted during their working life) and made of materials that are easy to recycle.

The targets of the ESSIAL consortium include:

  • reducing iron losses due to the magnetic reversal process by 20% (i.e., excess magnetic losses)
  • controlling and decreasing mechanical vibrations and noise by 20%
  • making it easier to apply/remove the insulating layer for a sustainable manufacturing process
  • integrating new laser processes with a maximum price increase of 10%
  • implementing innovative and unconventional technologies along the European manufacturing value chain
  • transferring the ESSIAL technology to European clusters and businesses

Achieving these goals will help Europe reach its energy transition targets while strengthening the European industrial base.

The ESSIAL consortium comprises research centres and businesses that together cover the entire value chain for soft magnetic materials, with all the necessary resources to conduct the project.


Soft magnetic materials, made from stacks of steel sheets separated by insulating layers, are becoming crucial for a wide range of end-user industries, for applications based on electrical components and machines, such as transformers, sensors, actuators, motors and generators.

Experts estimate that the market growth rate of soft magnetic materials will increase by 7.8% per year in coming years! However, the technology used to produce steel sheets causes huge energy losses (iron losses, in addition to copper and mechanical losses) and noise (due to induced pressure and vibrations).

Our role
