At start time tStart1 three-phase voltage is supplied to the induction machine with sliprings; the machine starts from standstill, accelerating inertias against load torque quadratic dependent on speed, using a starting resistance. At time tStart2 external rotor resistance is shortened, finally reaching nominal speed.

Simulate for 1.5 seconds and plot (versus time):

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

Default machine parameters are used.
