Information

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

At start time tStart single-phase voltage is supplied to the induction machine with squirrel cage; the machine starts from standstill, accelerating inertias against load torque quadratic dependent on speed, finally reaching nominal speed.

Default machine parameters are used.
