AVMT POWERPLANT ELECTRICAL (DC GEN/
ALternator)
1. What is the 4 MAJOR components of a DC GEN?: Brushes, Frame, Armature, Windings
2. How does a generator operate ( what does it do to produce Voltage): Gen- erates Voltage by
passing conductors through lines of flux. Generators convert mechanical energy to eletrical energy
3. Name what each finger denotes when using the left hand rule?: Thumb = Conductor
Index = Flux lines moving foward
Middle finger = induced emf
4. How is the output of a generator varried?: By changing the RPM of the armature
Chaning number of windings
Adjusting the stregnth of the magnetic field
5. What is used in a DC generator that changes the field strength: CR = Current limiter
6. Name the two posts on a generator and distinguish which is the input and output: Field = input
Armmature = output
7. In the Phase windings, what is used to counteract the armature reaction?-
: Interpoles are used in the phases
8. Describe what residual magnetism is.: Remaining magnetism after electro magnetizing
9. the field post is made of two components: Pole shoe Field coil
10.what will happen to the output of a generator if there is more fields?: The out put will be
greater because there will be a greater amount of lines of flux bein cut through
