Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

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:
- Crossing
- Permeance
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

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

Corrected wrong parameter descriptions, see ticket #1003
Extended machine models towards phase numbers to greater or equal than three, see ticket #990

Corrected bug in calculation of core conductance in SymmetricPolyphaseWinding: the wrong calculation G=(m/2)*GcRef/effectiveTurns^2 is now replaced by G=(m/2)*GcRef*effectiveTurns^2

Naming and documentation of PartialTwoPort is exchanged by PartialTwoPortElementary to match the naming conventions of Rotational.Interfaces and Translational.Interfaces
Fixed a broken link and updated documentation
Adaptions to Complex SIunits

Changed symmetric polyphase winding model
- Added zero sequence inductance based on zero inductor
- Replaced electrical model of stray inductor by stray reluctance model
- Integrated cores losses and heat port
Added rotor core loss parameters in induction machine with slip rings
Renamed heat ports of single-phase winding and symmetric polyphase winding
Relocated core losses between zero inductor and stray reluctance model in the magnetic domain
Renamed instances of stator and rotor (winding) models in each machines
Added magnetic potential sensor
Removed state selections
Updates due to changed loss variable and heat port names in Electrical.Machines
Added machine specific output records to summarize power and loss balance
Updated images of Users Guide
Improved performance due to annotation(Evaluate=true) added to the parameters of the single-phase winding
Reduced number of states in symmetric cage model by introducing an additional non-grounded star connection

Renamed all parameters windingAngle to orientation. The following classes are affected:
Update due to changed class names in Machines.Icons
Using HeatTransfer.Interfaces.PartialElementaryConditionalHeatPort instead of Analog.Interfaces.ConditionalHeatPort in EddyCurrent
Added modelica:// to all Modelica hyper links
Fixed bug in displayed parameters of EddyCurrent
Updated some images (and renamed image file LossPower.png to lossPower.png)
Exchanged positive and negative stator ports of RotorSaliencyAirGap model, adapted equations accordingly and updated code documentation.

Added stator core, friction, stray load and brush losses to all machine types based on loss models of the Machines library.
Changed parameter of EddyCurrent model from R to G
Fixed wrong sign of internal quantity tauElectrical, model behavior does not change
Rewrote equations of electromagnetic coupling to look more elegant
