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 asynchronous 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.
