A self-excited DC shunt generator is delivering 20 A to a 100-V line when it is driven at 200 rad/s. The magnetization characteristic is shown in Figure P17.20. It is known that Ra = 1.0 Ω and Rf = 100 Ω. When the generator is disconnected from the line, the drive motor speeds up to 220 rad/s. What is the terminal voltage?
