Hi folks, am new to motor control. I have to calculate core loss by
this params: s=0.06; Un=220v; pf=0.619; f=50Hz; Zn=118.280 ohm;
Rs=10.2 Ohm; Rr=10.52 Ohm; Xls=8.17 Ohm -> Lls=0.026 H; Xlr = 19.16
ohm -> Llr=0.061 H; Xm=143.57 -> Lm = 0.457 H.
So haw to find Rc ???
I try this from T-shape circuit:
rm=E1/Ic; Ic=If-Im; Im=E1/jXm; If=I1-I2; I2=?
But now i have to find rotor current and this is problem. Please can
someone help me this is very important for me. Haw to find, only by
this params, Rc or I2 ( after that i will calc it by equations i
show).
Thanks to everybody who read my problem.

What may ask would you need to know that for?
