Steady-state characteristics of the induction machine

This is a Java Applet created using GeoGebra from - it looks like you don't have Java installed, please go to

This set of animations provides a visual process for examining (on the fly) the effects of changing the values of the parameters of an induction machine on the torque, current, and speed characteristics. These parameters expressed in per unit (Vs ωs Rs Rr Lsl Lrl Lm ) may be adjusted separately or in combination by accessing the pertinent sliders. The slider ωs effectively represents the voltage-to-frequency ratio tool needed to model variable-voltage, variable-frequency operation.
