Magnetism with the magnet of a rotor
(For voltage establishment)
It is work of AVR connected to supplement winding, and is a brush.
Direct-current electricity controlled by
the field winding through the collector ring is sent
AVR controls an AVR output to .
detect output winding voltage
and to become stipulated voltage
Output winding voltage establishment
A rotor iron core is magnetized
powerfully
Voltage occurs in auxiliary
winding.
The voltage of output winding
rises.
(Rated voltage)
Load current flows into output winding.
The magnetism of a rotor increases
The power surge of output winding
As for output voltage, change of load hardly changes, either.
AVR makes the current of a field winding
increase through a brush and a collector
ring, when output voltage falls.
Sag of output

The control method of a generator
ａ）
Self-excitation action
If a dynamo is driven and it becomes with an engine more than specified speed, as shown in the following
figure, a self-excitation action will work, and it will generate.
b
）
Voltage compensation action
Although the voltage of regulation to output winding occurred by the self-excitation action of the preceding
clause, if external load is connected to this, as shown in the following figure, a voltage compensation action
will work, and it will prevent the fall of output voltage
