Information

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

This package contains models of synchronous machines, based on space phasor theory:
  • SM_PermanentMagnet: synchronous machine with permanent magnet excitation, with damper cage
  • SM_ElectricalExcited: synchronous machine with electrical excitation and damper cage
  • SM_ReluctanceRotor: induction machine with reluctance rotor and damper cage
    i.e., a squirrel cage rotor with magnetic poles due to different airgap width
These models use package SpacePhasors.
Please keep in mind:
  • We keep the same reference system as for motors, i.e.:
    Positive RotorDisplacementAngle means acting as motor,
    with positive electric power consumption and positive mechanical power output.
  • ElectricalAngle = p * MechanicalAngle
  • real axis = d-axis
    imaginary= q-axis
  • Voltage induced by the magnet wheel (d-axis) is located in the q-axis.
