Draw Equivalent Circuit Of Induction Motor. The forward and the backward flux induces a voltage e mf and e mb respectively in the main stator winding. As a result the three phase induction motor can be considered as being equivalent to a transformer having an air gap splitting the iron portions of the magnetic circuit carrying the primary winding and secondary winding.
Should complex representation be used then phase shift power factors etc. In consequence no matter what the value of slip the magnetic fields of the stator and rotor are synchronous with each other. The stator model of an induction motor consists of a stator phase winding resistance r 1 a stator phase winding leakage reactance x 1.
It is relatively straightforward to obtain the equivalent circuit parameters by testing.
The equivalent circuit of a single phase single winding induction motor with the standstill rotor is shown below. Typically this would involve a d c. These two components appear to the right of the machine model. It is relatively straightforward to obtain the equivalent circuit parameters by testing.
