1. Elec467 Power Machines & Transformers Electric Machines by Hubert, Chapter 12 Topic: Self-excited and compound generators, load distribution.

2. Self-excited shunt generator

3. Changing the output voltage

4. Flux and current relationship There is a incorrect connection in one of the above drawings. Which one is it? Examine the circuits using the right-hand rule for current flow.

5. Short on the output

6. Compensating windings Compensating winding are the stator coils wired to a separate DC source.

7. Magnetization curve

8. Adding a series inductor to a self-excited generator

9. Motor design considerations

10. Effect of adding a resistor to the series inductor of a self-excited generator 1.Adding a series inductor will increase the current flow. 2.Adding a resistor across the series inductor will change the rate at which the generator increase the current.

11. Protection circuit prevents current reversal
