Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
At start time tOn three phase voltage is supplied to the
asynchronous induction machine with sliprings.
The machine starts from standstill, accelerating inertias against load torque quadratic dependent on speed,
using a starting resistance. At time tRheostat external rotor resistance is shortened, finally reaching nominal speed.
Simulate for 1.5 seconds and plot (versus time):
