Rewinding a Large Motor at KOFFLER
ฝัง
- เผยแพร่เมื่อ 1 ม.ค. 2013
- bukaymedia.com This shows how a large motor is re-wound, serviced, and tested. The scale, complexity, teamwork, and know-how required by the people at the KOFFLER Electrical facilities in San Leandro, CA. is amazing! Everything, from making the wire coils to the Vacuum Pressure Impregnation (VIP) process, is done at this one location. KOFFLER's website is at www.koffler.com
The motor in this video is used to power a pump that removes water from a submarine dry dock facility at Pearl Harbor. Another video at bukaymedia.com/koffler.htm documents how the large pump impeller powered by this motor is balanced.
This movie is a good example of how web videos efficiently communicate a company's unique capabilities to its customers and prospects. Can you imagine trying to tell this story in 5 minutes without a video? - วิทยาศาสตร์และเทคโนโลยี
I used to work on a submarine drydock in the UK. It was four sections of a much longer WWII battle ship dry dock. Each section had two alternators, neither of which were as large as the synchronous motor in the video. Very impressive facility and personnel at KOFFLER Electric.

Always nice to see guys who are proud of their work, and it shows here....
What a great trip down memory lane this is. I started my armature winder apprenticeship in Manchester UK in 1960. Worked on small motors to 500 MW sets, motor testing, through college, drawing office, senior electrical engineer and qualified teacher. Hard work but creative and a great start in life! Loved it. The world should have an annual Tesla day. Best wishes?
Amazing video and amazingly talented people doing the work, Thank You for this!
work
that was awesome, thank you. The detail and painstaking work, wow
Love working with these guys! Real professionals!!!
Excellent video and handcrafted work ! Thanks for taking the time to show us. True professionals !
I work for a company that makes the coils that go into the motor always love seeing what happens after we get finished and send them off
Me too..i work in Birmingham...forming the stator coils
Awesome, i'm studying in electrical motor. And found this video. Thank you!
Hi Ari,
I'm glad it was helpful! I also learned a lot about motors while filming these videos! Sort of like being a kid in a candy shop!

Chuck Norris want a 5 - 7 times this motor size and strength for his pocket sized cooling fan.
Please help him build that.
@@noorazmi2329 Chuck doesn't have to cool his nuts. His nuts cool him.
I know this is old but where are you studying
I'm jealous of the workers depicted in this video. They are skilled, and have the opportunity to work as part of a team in a technical field.
Rewinding the rotor, balancing the rotor, rewinding the stator, baking the stator then sealing the stator. I loved that job.
What an amazing job you guys do, very impressive.
I was truly amazed while filming their work! So hands-on, and must be done so precisely! Thanks for watching.
Mike

Rosie O’Donnell thanks you guys for fixing her treadmill motor.
"Hello? Yes, this is 1994. Who may I ask is calling? ... ... ... No thanks. We won't be needing that joke back, but thank you for calling."

Very nice video and the work and craftsmanship is great!
great job ! very professional.
Brings back memories of my apprenticeship days . Many hours goes into a build project like this . Solid bar windings building and insulation took over a month for a similar size stator . About 3months all up just for the stator rebuild of similar size .
many hours
Amazing work!!
As an engineer, I find this video orgasmically interesting!
As an electrical engineer, this video is a lot of fun to watch.
I was mesmerized, amazing work!
Very Very Impressive!
Very cool, my hands hurt watching this but i want to jump in!
Wow! Great work.
nice work fellas!
Who's looking for some of that anti-corona epoxy in 2020?
All of us
@k cookers Hey how much u want for it?
@Samuel Lynch Yes, we also know that corona is an electrical effect of magnetic fields. Our sun gets/has a corona around it. The virus when viewed through a microscope has some resemblance to the sun with it's corona and this is where the virus got it's name.
@Samuel Lynch sir I think you missed the joke
@@aculasabacca No, it is all about high electric field (has nothing to do with magnetic field). At sharp points, the electric field is so high it causes ionization of the air. Corona refers to crown, king's and queen's crown has lots of spikes and hence the name.
Wow, been along time since I've seen all those guys!! Pretty cool video
2:50 I think we could really use that anti-corona paint rn
XD silly you. It’s to prevent sparks.
Great job with the craft. The video edit was nicely done too
This is real world work. Good job men.
great job, thanks for the video
Looks like excellent craftsmen. Nice job
well done. Reliable workshop.
Wow, that is a beautiful shop and every one of those guys is a true master.
WOW amazing art work
A good job by skilled workers!
worker
I apliciate that, loving this work, from Tanzania
Exlent very useful understanding large scale motors working and inside structure
Amazing.
Is an electrical engineer symphony.
QUALITY JOB! +1M likes to the workers!
i m interested. i love this kind of rewinding works
Really nice craftsmanship.
Great job on the video production!
Thanks Allen!
Music was way too loud in distracting a lot of these types of videos where they show things being built they don't play any music at all instead they amplify the sounds of the shop really helping you put yourself there
this is really cool!
Awsome work gents!!
Nice video, I rewound my share of 2300 - 4160 volt stators, but the slip ring rotor was a very nice looking rewind. Of course we did more Mush / Random stators, just weren't that HUGE!!! LOL. My step dad worked at Vincent Electric in Oakland for 30 plus years Don Rader he was a Damn good winder. I retired 5-yrs ago, sold my business to a kid that I hired in 1979 and I still go in to visit and once in a while still stuff a cake job. I don't miss the knuckle busters.
Paul Monaco i just lost my job with GE doing this kind of work, even bigger motors than these, can i ask what kind of money a "winder" makes down there?? for the record i was getting 33/hr canadian, other places seems to pay about the same up here... just curious
Huge respect for you, sir.
@@DrunkenGuitarGuy I just your question, well in Portland Oregon the winders get paid a lot less. The range is from $17.50 -hr for beginner to $38.00 for an " OLD PRO " but the OLD guys always got plenty of OT. So they were really making $125K to $175K a year. In California where my step Dad worked I guessing back then he was in the $40.00 to $46.00 per hour range, Today they maybe $50.00 to $55.00 hr. The shop rate is $135.00 hr. so I'm guessing they make a little PROFIT!!! hahahahahaha.
Nice
I did not know how these big motors were repaired
Making money the old fashioned way, delivering true value to the customer. Great going!
So true!
Nice video
great work,and this video has study how to made of generator
Just love those 1st few turns on the balancer.... will it stay on the rollers I ask...
Professionalism and technology.
Beautiful!
Excelente trabajo...muy prolijo
Me encanta este trabajo!
Such work is always forced to stand still open in amazement mouth. Great, very expensive equipment.
And so much knowledge and skill is required to do the job correctly!

That's a cool job!
superb video...!!
beautiful craftsmanship The knowhow is tremendous
Very good job
my table saw ain't gonna bog down now
Nice job! I hope that i could join that company :)
The company I work for has made stator coils for y’all before!!!!
Fantastic to see such skills, ask a kid what an armature winder is - clueless would be 1st guess.. Just loved the 1st run up on the balancing machine... 50/50 as to whether it'd come off the rollers. Been nice to see the finished motor work full belt emptying the dry dock some massive pump I imagine..
Why would a kid be expected to know that?
that was awesome
I used to do this on a summer job in Midland Texas..lower scale though...220 v motors..
Tony Avila west Texas baby I’m from big spring
Nice image of the Russian sub at the beginning.
Russian subs are the nicest in the world)
Best submarine builders in the world
Fastest Sub K-222
Largest sub Typhoon Class
And they have great stealth subs as well
The new Borei is lightly smaller but far more capable than the Typhoon
While all valid points... I don't expect to see a Russian sub dry docked at Pearl Harbor so we can give it a once over.
Barnekkid
@@ShainAndrews Well...I guess if the Russians fork over some cash, they could slap a new coat of paint on it or something.
I love rewind this is
my second love.
Amazing work, great job guys.
Will that fit in my Nissan Leaf? Seriously though that looks like crazy work. Need to always be on the ball since if you mess up it throws off the whole motor and you have to start over.
Very impressive!
Cant imagine how expensive the rewinding must have been. Damn!
Nice to see a motor being rewound in America, by Americans with the proper tools and techniques. Too many of those dirt floor India rebuilds on YT.
Amazing Job guys !!
Excelentes profissionais
Es lo que buscaba,es mi trabajo en equipo,I cant handle it on My phone,I need My Own computer to stay enjoing and learning thank you very much cause you share all of this with the public,make me feel special.
good video
Wonderful motor!
do you guys ever come in with a hangover, and just stare at all those wires going, "What the fuck"?
How can we control run-out issue in vertical machines rotor.
And slip ring run-out in horizontal machines.
It love this work
Watching this and then watching a Bangladesh man do it in a dirt field is bewildering.
Holy crap that's big!
Wow , that is huge .
if you guys are looking to land your next major contract, the motor on my dremel has burnt out and needs replacing. The project is just in its early stages if youd like to send me your tender documents. Project budget is around $30
carpii 😂😂😂
intricate!
nice job
Such huge motors. Pump water out of oil drilling. Ship docks. Mostly used for salt production from near by sea.
really it was more than exlant , thanks for tecknology
Super
i worked at southern electric coil in Hammond Indiana for almost 20 years i made lots of formed coils like that.
I'm from Calumet city. Small word huh?
How did you come to doing this kind of work? Is it something you aimed for or kind of just fell into?
I work at CMI in Birmingham...we make coils like this also....
حقيقة عمل يستحق التقدير والاحترام
Super duper quality
Awesome..!!!
thank you this video..nice work..god bless..all!
Thank you for watching it, and for your kind remarks!
Awesome!
So nice
Great power american this motor what;s capacity in HP and kv requiered in your start ... thank Michael for your videos ...
Incredible
Nice job!!
This is crazy hands on labor .
It's fun work, did it for USN and USAF.
