I have to made an Induction Motor Model by myself and my first step was to just replicate an already existing example i.e. Electrical.Machines.Examples.AsynchronousInductionMachines.AIMC_DOL. Now I have replicated it but I can't parameterize the AIM_SquirrelCage because I can't set all the default values in it. Please see attachments. And help thanks.

  • I assume that Modelica is an electrical/physics modeling/simulation package of some sort. (Google suggests similar to Simulink.) There are a few folks around here who use it (based on a search of prior questions) but a lot of folks have no idea what it is and thus consider your question too vague. Your question is a bit light on input data, regardless. – Hot Licks Jul 18 '13 at 01:23
  • I agree that your question is a bit light on input data, in order to help you we need at least the modelica code of your model. Which modelica-based simulation tool are you using? Which version of the Modelica Standard Library? These errors refers to the check of whiich model (AIM_SquirrelCage, or whole InductionMachine)? – Marco Romanoni Jul 19 '13 at 14:11
