Abstract :
Most textbooks on electric machines present a classical five-element constant impedance equivalent circuit for modeling polyphase induction machines operating under balanced polyphase sinusoidal steady-state conditions. Yet it is known for cage rotor machines that the rotor element impedances vary significantly with rotor frequency. Research is in progress to determine a better AC equivalent circuit model, balancing accuracy against practicality of use and data acquisition. This paper provides a qualitative assessment of several advanced machine models
