Information

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):

• aimcM|M3.tauElectrical: machine torque
• aimsM|M3.wMechanical: machine speed
• feedback.y: zero since difference of three-phase current phasor and scaled polyphase current phasor are equal
