Offer Description

Additive manufacturing (AM) has led to a revolution in mechanical design by allowing the production of parts with complex shapes and original geometries. However, in the field of electrical machines, AM remains underdeveloped. The studies are driven by the demand for mechanical-electrical energy conversion machines, particularly in the context of electric vehicles, with the desire to have a high specific power, associated with low losses. Thus, an electrical machine is composed of different subsystems on which AM technologies would bring decisive innovations.

The magnetic circuit is a component of interest, in particular the stator (fixed part) composed of ferromagnetic elements, currently designed through a stack of insulated laminated sheets.

The ANR FALSTAFF project aims to explore new ways of producing these elements, freeing themselves from the constraints of current geometries, while preserving components properties, particularly in terms of magnetic efficiency.

The FALSTAFF project aims to explore new innovative ways of producing ferromagnetic alloys, in the form of 3D laminated components, combining magnetic and insulating structures.

Two methods will be proposed, by the development of internal porosity or by the combination of two materials, and through the exploitation, respectively, of the L-PBF (Laser Powder Bed Fusion) and DMD (Direct Metal Deposition) processes.

Similarly, two materials must be investigated in the context of the part construction, iron-silicon and iron-cobalt-vanadium alloys.

Laminated test pieces will be produced, exploring different parameters and manufacturing strategies also integrating the required heat treatments. The parts produced will then be characterized, in order to analyze the link between process parameter and microstructural, chemical and mechanical properties, with the aim of finding the optimal process conditions. Ultimately, the project aims to demonstrate the industrial interest of producing ferromagnetic components by FA process.
