Good Day All and Happy New Year!
Now I have been struggle to fully understand what is meant by the ACIM rotor magnetizing current for a while now. Now I have been able to grasp this much, that this vector is made up of the stator and rotor(referred to stator) currents vectors under. Now when applying the Dynamic Model equations for the ACIM I also know that as long as the stationary reference frame is used, it allows you to simply divide the rotor flux by the magnetizing inductance to obtain the magnetizing current vector of the rotor. Now I think I am having trouble understand it's application to Vector Control of the ACIM. I can use my equations to obtain this magnetizing current but how exactly do I attain this magnetizing current in practice? If I really can? Am I over looking something? Be sure to correct me if I have said something wrong.
Lets say I am using Direct field orientation for instance. Do I obtain this magnetizing current after I transform the stator currents I measure from the motor?
Extremely lost for the New Year! Help
