At start time tStart three-phase voltage is supplied to the induction machine with squirrel cage, first star-connected, then delta-connected; the machine starts from standstill, accelerating inertias against load torque quadratic dependent on speed, 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.
