Information

This example compares a time transient and a quasi-static model of a polyphase induction machine. At start time tOn a transient and a quasi-static polyphase voltage source are connected to induction machine with sliprings. The machine starts from standstill, accelerating inertias against load torque quadratic dependent on speed, using a starting resistance. At time tRheostat external rotor resistance is shortened, finally reaching nominal speed.

Simulate for 1.5 seconds and plot (versus time):

• currentRMSsensor.I|currentSensorQS.abs_i[1]: (equivalent) RMS stator current
• ims|imsQS.wMechanical: machine speed
• ims|imsQS.tauElectrical: machine torque

Default machine parameters are used.
