Machines

• Examples: test examples
• BasicMachines: basic machine models
• Sensors: sensors, usefull when modelling machines
• SpacePhasors: an independent library for using space phasors
• Interfaces: Space phasor connector and partial machine models

• number of phases (of induction machines) is limited to 3, therefore definition as a constant m=3
• phase symmetric windings as well as symmetry of the whole machine structure
• all values are used in physical units, no scaling to p.u. is done
• only basic harmonics (in space) are taken into account
• waveform (with respect to time) of voltages and currents is not restricted
• constant parameters, i.e. no saturation, no skin effect
• no iron losses, eddy currents, friction losses;
  only ohmic losses in stator and rotor winding

You may have a look at a short summary of space phasor theory at http://www.haumer.at/refimg/SpacePhasors.pdf

• generalizing space phasor theory to m phases with arbitrary spatial angle of the coils
• generalizing space phasor theory to arbitrary number of windings and winding factor of the coils
• MachineModels: other machine types
• effects: saturation, skin-effect, other losses than ohmic, ...
