Comparison of Induction Machine Equivalent Circuit Models

چکیده
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 j-equency. Research is in progress to determine a better ac equivalent circuit model, balancing accuracy against practicaliv of use and data acquisition. This paper provides a qualitative assessment of several advanced machine models.
