Equivalent circuit of a three phase induction motor

induction motor

So, i know that a equivalent circuit of a single phase of a three phase induction motor is just like a transformer equivalent circuit when it is at standstill. When, however, it is rotating the frequency dependent quantities like voltages, currents, reactants change as they should change. But, the thing with induction motor is, the input power and the output power, when rotating, are not same(because some power is given to the shaft) unlike transformer. In transformer i used this property to create equivalent circuit referred to primary side. Now, how can i further simplify the equivalent circuit of the three phase motor (equivalent circuit referred to stator). enter image description here
