Exporting parameters from FEM.

Depending on the application there are various parameters that can be calculated in a FEM analysis and exported to Caspoc. In the following we discuss some typical applications and what should be exported from FEM.

The applications discussed below are:

• Inductance
  Exporting the values of inductors or coupled inductors.
• Capacitance
  Exporting the capacitance to be used in any circuit simulation
• Transformers
  Exporting the primary and secondary inductance, coupling as well as the winding resistance of transformers and coupoled inductors
• Planar transformer
  Winding inductance of the primary and secondary side of aPCB traces
• BLDCM Brushless motors
  Back emf and torque look-up tables
• PMSM Permanent Magnet Synchronous Machines
  Back emf and torque look-up tables and secondly the current dependent winding inductance.
• Induction machines
  Saturating magnetizing inductance
• Wireless power transfer
  Transmitter and receiver winding inductance as well as coupling as function of distance and displacement
• Heatsink
