Information

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

An ideal frequency inverter is modeled by using a VfController and a three-phase SignalVoltage. Frequency is driven by a load cycle of acceleration, constant speed, deceleration and standstill. The mechanical load is a constant torque like a conveyor (with regularization around zero speed).

Simulate for 20 seconds and plot (versus time):

  • currentQuasiRMSSensor.I: stator current RMS
  • aimc.wMechanical: motor's speed
  • aimc.tauElectrical: motor's torque

Default machine parameters are used.
