At start time tStart1 three phase voltage is supplied to the asynchronous induction machine with squirrel cage via the transformer; the machine starts from standstill, accelerating inertias against load torque quadratic dependent on speed; at start time tStart2 the machine is fed directly from the voltage source, finally reaching nominal speed.

Simulate for 2.5 seconds and plot (versus time):

• currentQuasiRMSSensor.I: stator current RMS
• aimc.wMechanical: motor's speed
• aimc.tauElectrical: motor's torque

Default machine parameters are used.
