What you are showing is correct, the values maybe a bit skewed, and it might help if you explained why the values are different.

Because here i am not showing secondary mutual flux linkage due to rotor which is virtual and can be imagined by 1 phase transformer at rotor as secondary side of transformer this is a cause of values are different

That is part of the answer. The simplest answer would be to say, with out the capacitor and auxiliary winding, there is no guarantee of the direction the motor would run. The capacitor and auxiliary winding shift the phase of the applied power to make a sure determination of direction of rotation. The size and power rating of the auxiliary winding is limited by the physical sizing of the capacitor (this physically limits the power available to the aux winding).

You're right

There are a lot of more knowledgeable people than me on this site, all one has to do is ask.
