Induction machine with squirrel cage and Steinmetz-connection

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

Information

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.
