At start time tOn
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 tRheostat external rotor resistance is shortened, finally reaching nominal speed.
Simulate for 1.5 seconds and plot (versus time):
