Asynchronous induction machine in quasi-stationary mode

Extends from Modelica.Icons.Example (Icon for runnable examples).

Information

This example deals with a three-phase asynchronous induction machine. It consists of a simple electrical circuit to drive the motor via a variable voltage source. Besides the shaft's interia and a damper component, a variable time-dependent applied torque is used as load.
The machine's electrical subsystem is connected to a three-phase voltage source which is the same as being connected to three single source components. The three-phase source works with variable amplitude and phase. It is governed by two input signals (one for amplitude, one for phase) for holding symmetrical conditions.

Simulate until 40 s.

Plot in seperate windows:

  • signalVoltage.V  and  torque.tau  versus "Time" to see the input stimuli
  • omega and  aIM_3ph.inertiaRotor.w  or  aIM_3ph.s  versus "Time" to get the slip of the machine (s=(omega-w)/omega))
  • completeElPwr  and  aIM_3ph.P_mech  versus "Time" to see the power balance
always as a sequence of steady states.
