At start time tOn voltages are supplied to the
induction machines with sliprings. The two machine start 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. Two equivalent machines with different numbers of phases are
compared and their equal behavior is demonstrated.
Simulate for 1.5 seconds and plot (versus time):

current phasor and scaled polyphase current phasor are equal
