Version 3.2.3, 2019-01-23
  • Fixed propagation of excitation leakage factor, see #2403
  • Added model of electrical excited synchronous machines, starting direct on line, see #2388
  • Unified communication interval, see #2279
  • Unified simulation tolerances, see #2278
  • Added more examples from Machines.Examples, see #2276
  • Replace wrong permeance image in documentation according to #2208
  • Added obsolete annotation to SymmetricMultiPhaseCageWinding_obsolete and SaliencyCageWinding_obsolete, see #1536
  • Updated documentation of Short, Idle and PermanentMagnet
  • Added new components:
  • Removed parameter text from icon layer for reluctance and permeance model
  • Restructured cage models with reluctance instead of inductance model according to ticket #1536; the re-structuring of the model required to change the initial conditions of the included examples, since the number of rotor states is reduced by new implementation
  • Some more bug fixes according to #1226, since not all reference orientations have been correct
  • Added variables for magnitude and argument of complex magnetic potential difference and flux, see #1405
Version 3.2.1, 2013-07-31
  • Bug fix of wrong orientation of squirrel and damper cage models, see ticket #1226; this also includes the removal of the rotor cage heat sensor which previously has been used
  • Bug fix of conditional initialization of examples, see ticket #1223
  • Fixed missing default parameter TpmOperational in ambient of PM synchronous machine, see ticket #1216#1216
  • Added voltages, currents, complex flux and magnetic potential difference as global variables in polyphase converter
  • Added two more component examples, showing the equivalent nature of electrical and magnetic domain
Version 2.0.0, 2013-03-10
  • Corrected wrong parameter descriptions, see ticket #1003
  • Extended machine models towards phase numbers to greater or equal than three, see ticket #990
Version 1.7.3, 2013-02-25
  • Corrected wrong parameter description
Version 1.7.2, 2011-06-28

Version 1.7.1, 2010-09-03
Version 1.7.0, 2010-05-31
