A bobbin is a spindle or cylinder, with or without
flanges, on which wire is wound. The primary and
secondary is wound on the bobbin.

4. Shailesh Khaparkar Gyan Ganga College of Technology, Jabalpur
This machine is used to wind the number of turns
on the bobbin.

5. Shailesh Khaparkar Gyan Ganga College of Technology, Jabalpur
Transformer core is made from E & I stamping. The
material used for making E & I stamping is CRGO silicon
steel for reducing eddy & hysteresis loss. With the help of
E & I stamping the shell type core is constructed, the
function of core is to set up & provide a path for flux.

Step I :- Fix the bobbin on winding machine as
shown in image below.

7. Shailesh Khaparkar Gyan Ganga College of Technology, Jabalpur
Step II :- First select the copper wire and wind the primary
number of turns as per design requirement on bobbin. The number
of turns wound is shown by the counter of the machine.

Step III :- After completion the number of turns of
primary winding, insulation paper is wrapped on the
primary winding . This insulation paper isolates the
primary & secondary windings.

Step IV:- After completion of wrapping the
insulation paper, start winding the number of turns of
secondary winding as per design requirement .

Step V:- After completion of winding the number of turns of
secondary winding, take out bobbin from machine. Now start inserting E
& I stamping in bobbin this should be done in almost alternate fashion.
The construction of shell type core by using E & I shape stamping as
shown in image below.

Step V:- After completion of winding the number of turns of
secondary winding, take out bobbin from machine. Now start inserting E
& I stamping in bobbin this should be done in almost alternate fashion.
The construction of shell type core by using E & I shape stamping as
shown in image below.

Step V:- After completion of winding the number of
turns of secondary winding take out bobbin from machine.
Now start arranging the construction of shell type core by
using E & I shape Stamping as shown in image below

Step VI :- After constructing the core tight
the core with the help of screw & bolt along with
the supporting frame.

Step VII :- Now apply 230 volt to primary
winding and check whether you get desired value
of secondary voltage.
