Question: 2 . A dc machine ( 5 . 5 KW , 2 2 0 V , 1 5 0 0 rpm ) has Ra =

2. A dc machine (5.5KW,220V,1500rpm) has Ra =0.8 ohm and Rfw=160 ohm. The machine is driven at 1500 rpm and is self-excited. The field control resistance, Rfc, is adjusted to provide. a no-load terminal voltage of 200v. Determine the value of Rfc. Determine the terminal voltage at full load If(Ar)=0.05A. Use the attached magnetization curve.
