poles

armature coils

parallel path

brushes

increase the flux around the conductor

decrease the flux around the conductor

rotate the magnetic field over the conductor

set the pole and armature to touch each other

The armature core is not properly laminated

The generator is kept idle for a long time

The armature resistance is more than 1 ohm

Incorrect brush position

inserting compensating winding

providing inter poles between the main pole

shifting the brush position from GNA to MNA

increasing the ampere - turns in the field winding

ebonite

mica

empire
