ATOP: topological optimisation software for the design of magnetic structures
Content created on
The “all-electric” trend is gaining ground in a number of sectors, including the space industry, driven by Hall-effect thrusters, and the automotive industry, with electric cars. As a result, R&D teams have to rapidly come up with magnetic structures that meet a wide range of constraints (reduced mass and volume, lower costs, etc.). The tool developed is topological optimisation software for the design of magnetic structures.

Description
Topological optimisation software for magnetic circuit design
Key points:
- Software environment consisting of an algorithmic suite implemented in a multiphysics simulation solver
- Generative design software to overcome the subjectivity of the designer
- Enables the dimensioning of structures with complex magnetostatic behaviour to be modelled.
Technical specifications
- Functional constraints: Dimensional, magnetic, physical, structural, etc.
- Type of devices: all devices with a magnetic structure (soft or hard ferromagnetic materials and coils)
- Gain: Considerable reduction in the weight of parts (elimination of unnecessary material). Up to 80% for Hall-effect thrusters
- Stress optimisation
