MagNet Version 7.1 Now Available

Magnetization

MagNet v7.1 allows users to simulate the magnetization process: the magnetic field magnetization of the work piecestrength inside the permanent magnet component will be determined by the magnetization pattern and source current in the magnetizing coils. The result will be a permanent magnet for which each point inside will have a different recoil loop depending on the flux density that it has reached during the magnetization process

Further Improvements to Multicore Processors

MagNet v7 introduced new parallel computing 3D solvers which are optimized to take full advantage of multicore processors. For computational intensive design problems, the simulation time is reduced significantly due to better management of the cores. The new release expands on the software’s support for multicore processing:
  • Parallel computing 2D solvers (static, AC, transient and transient fields with moving components)
  • Running concurrent sessions of MagNet solvers in 2D or 3D

Engineering Efficiency with Multicore

With this new feature, users can control the number of cores dedicated to a particular 2D or 3D solve, increasing the number for more computational demanding problems, or distribute the multicore processing to run several concurrent sessions of MagNet. For larger core machines, several concurrent sessions of multicore solves can be taking place.

Other new features include:
  • Modeling Nonlinear Surface Impedance: the effects of nonlinear BH properties are accounted for when computing surface impedances
  • Faster core loss calculations
  • Improved meshing and remeshing in 2D
  • New Magnequench NdFeB magnets and other refinements to materials database
MagNet version 7 is now available. Maintained clients can visit support.infolytica.com to download version 7.1 or read the Release Notes for full details.

MagNet's magnetization pattern predicting capability is used to design a Halbach cylinder BLDC servo motor in this example. A four pole 12 slot, 3 phase machine is designed here including accurate modeling of an external, impulse magnetization of the Halbach cylinder. Presented below is the magnetizing fixture, the resulting magnetization pattern and performance of the servo motor.
