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.
