QuickField analysis for Electromagnetic Plunger design.

Informally speaking, the usual purpose of a magnetic system is to conduct the magnetic flux and deliver it to the specified place. The typical tasks in the magnetic systems analysis and magnetic systems design are:

  • calculate the overall magnetic reluctance of the magnetic system as well as reluctance of every its part;
  • find the magnetic flux distribution;
  • adjust the geometries and materials used in the magnetic system design to reach the specific flux values.

Magnetic system analysis software allows to limit the prototyping time and reach design goals faster and with higher accuracy. QuickField provides several modules for the magnetic system analysis:

  • DC magnetics - for static models, which may include non-linear materials, permanent magnets, currents and various boundary conditions.
  • Transient magnetics adds possibility to simulate the transient modes of the magnetic system operation and time-varying magnetic field sources.
  • Magnetic systems including time-harmonic alternating currents may be analyzed using the AC Magnetics module, which works faster than Transient Magnetics, but does not allow permanent magnets in the magnetic system description.
