At start time tStart voltages are supplied to the
polyphase induction machines with squirrel cage.
The machines starts from standstill, accelerating inertias against load torque quadratic dependent on speed, finally reaching nominal speed.
Three equivalent machines with different parameter ratioCommonLeakage
are compared.
Note that due to the mode of operation, the behaviour of all three machines is identical.
Only when fed by switching power electronics, parameter ratioCommonLeakage
is essential.
