Question
Flux density under trailing pole tips in case of generator will:
✓
Answer
- increase
LPT= leading pole tip
TPT= tailling pole top
Considering armature reaction.
where GNA=Geometrical axis
MNA=Magnetic neutral axis
here clearly see that TPT side flux increases due to armature in case of generator.
