Finite Element analysis
Finite Element analysis (FEA) or Finite Element Method (FEM) is probably the best and most powerful tool for magnetic design. Magma’s engineers are capable offering unique magnetic solutions, fitting tools and more, sharing our experience according to your company needs.
We conduct a series of tests to determine the magnetic properties for the design: Finite Element analysis, electromagnetic field motion mapping, magnetic field mapping, 2D and 3D modeling, magnetic properties within a range of temperatures, flux density calculation, Gauss measurements and physical strength of the magnet.
Finally, we offer an optimization of the design based on the results.
FEM analysis is a very strong tool to achieve the most accurate results, faster and to avoid prototype mistakes. In a nutshell, FEM analysis enable the designer to simulate the design concepts on the computer and get results (for example maximum torque of an electric motor), before building a prototype of this motor. From our experience, this kind of magnetic simulation have helped us solve many of our customer’s problems and helped save considerable amount of money. It is important to mention that the data that is calculated in our software is very accurate, meaning that prototype built with same parameters as the design (in our software) – gives practically the same results as per our design.
Magma uses Ansys Maxwell software for magnetic FEA analysis. Magma engineering team is able to make accurate representation of the complex geometry of the magnetic fields, calculate the effect of different material properties and give the customer a easy representation of the total solution.
