The torque-speed relationship as a general equation for torque as a function of slip is derived from the induction motor equivalent circuit. The induced torque is (7.5)τind=3VTHRTH+R2s2+XTH+X222R2sωsync where VTH, RTH, and XTH are the Thevenin equivalents of voltage, resistance, and reac...
Here electrical analogy of mechanical system is integrated with d-q equivalent circuit derivates from the stator frame of reference to create a complete equivalent circuit for three-phase induction motor which is suitable for dynamic simulation. Finally this paper presents results that validate the ...

An equivalent-circuit model of a linear induction motor is developed, using the rotary-motor model as a basis. The rotary-motor model is modified to account for the so-called `end effect and is used to predict output thrust, vertical forces and couples. These predictions are checked against ...
The equivalent T circuit of an induction motor is found in every engineering motors book, and is becoming increasingly important with the popularity of vector control. The values used in the circuit are used to dictate the necessary gating signals for the PWM inverter. It is the de facto stand...
