Training Life 1

Now start to post something regarding my training life
It actually would be a long post
but due to my laziness, please allowed me to separate to several parts!
I lazy to wait to pictures to upload bah! =S

Our first lesson is Motor Rewinding!

Ever seen a motor before?
How a motor look like?
Nah...Here it is..
""
"

Different brands of Motor (stator) in different size!
Huge one the weight might be heavier than 100kg

How to start?
First get a burned/ broken stator like this

Remove the unwanted/broken part

Ignore that fatty hand! That is not mine! LOL
Then it will be look like this.

Tools need as follow:

Next is the cleaning process
Remove the residue of varnish layer on the motor
Before that should jot down the thickness of copper wire used
and also calibrate the thickness of insulated paper by using micrometer

After all, cut the insulated paper with the paper cutter like this:

Fold the paper and insert it into the slots
the size and length of paper must fully fit the slots!

Now the papers are finished insert into the slots

Next step we come to rewinding coil!
The rewinding coil machine
(Notice: there also got a motor inside this machine)
Every machine need a motor to operate
Motor consider an important part of a machine
Without a motor, a machine can't work in proper way

Go get the proper/ suitable size of copper wire
For example: 0.85mm, 1.00mm...and so on

Then start rewinding to coil Like this:
Must hold the wire tightly if not it will loose to the wrong slot

Depends on the connection of the stator
(Star/ Delta/ Star-Delta)
Consider the step of the stator too
Eg: 1-8/1-10/1-8
The ready coil is now put into the slots as picture shown

This actually the most challenging progress
since the slots provided is quite small
must push the coil into the slots
And at the end the coil is getting thicker
and will be harder to insert the coil into the slots

There are 3 phase
separate the phases with insulated paper too like this:

After that wrap the wire ends with the wire cover

Next, tie up the wire so that it look neatly as the pic shown:

Tie both bottom and upper part
Tadaa..the side image:

Final step!
Apply the varnish all over the coil

END Of the process to repair the stator. =)

Here i add on some pictures :
After repair the motor, i found that

.
My hands/ fingers get hurts

Feel pain and sometime accidentally cut my finger!
My supervisor told me that
To become an NORMAL engineer
MUST tahan
MUST kotor
MUST kena cedera
MUST rajin
=.=||

The stators...
This indon guy is repairing his Huge stator
With large size of coil
This is the trolly which is use to hang/hold the BIg motor
Because too heavy, need to use this to move the motorMedium sized motor
The factory..
Tool box room
The forklift!
I wish someday..i can drive it! Hmmm..Joan on the car~~
Stay tuned ya..
to be continue..=)
