The constant-speed magnetization curve for a 25-kW, 250-V dc machine at a speed of 1200 r/min is shown in figure below. This machine is separately excited and has an armature resistance of 0.14 Ω. This machine is to be operated as a dc generator while driven from a synchronous motor at constant speed. a. What is the rated armature current of this machine? b. With the generator speed held at 1200 r/min and if the armature current is limited to...
