Hello everybody. I was wondering what the lg washers look like on the inside. What kind of suspension system does this washer use? What do the drive motor, pump assembly, steam generator and various parts look like? How do they operate? What do all the models look like on the inside particularly the wm2487? Do they use bearing oil or no. I understand that they were made in Korea. I would like to get a better understanding of how these washers are built so I don't always feel too uneasy of what seems to be flimsy quality. Thanks.

LG...
I have seen two types of motors used in LGs: belt drive with a brushed"universal"motor and some models with a direct drive electronic driven motor-direct drive is much quieter and allows special wash motions on certain machines.The direct drive motor consists of a drum about 10"diameter with magnets around the inside of the outer rim,a stator rimmed with electromagnetic coils fits inside the drum and is mounted to the outer tub.There is an old thread on here where a badly corroded spider is replaced on a direct drive LG-thread title is something like "meet horsey"Corrosion of the spider-usually of cast aluminum-is a common problem with front load washers,often a "death failure"with these machines when the spider corrodes and breaks-a variety of factors determines the severity of corrosion from minimal to severe.The pump in an LG is the usual wet rotor permanent magnet "magnetic" type.LG is made in Korea,started selling goods in the US~1982,selling mini fridges and small black&white TVs under the "goldstar"brand
No bearing oil-just greased ball bearings.

What does the 2487 look like on the inside? How big is the drive motor of this machine? I was under the impression that this is a direct drive. Where are the ball bearings? What type of grease do they use? What about the suspension system?

Google is your friend
Seriously Jerome, do some internet research. All these parts you want to see are readily available on the internet and Youtube.
Look up repair videos. Search for LG and Samsung patents in Google Patent search.
Look up repair parts via a model number search on RepairClinic.
I've been feeding my curiosity this way for years.
Why do you expect us here to spoon feed you EVERYTHING?

Go onto the internet and look up "using a washer motor as a power generator powered by wind or falling water"That may give you an idea what the DD washer motors are like.And these power ideas actually can work.So--some of the "scrap" value of DD washers is in their motors "recycled" for small power generators.Hint-go to a place selling the DD washers-LG or Samsung--Give the drum a good spin-the washer dial lights will come on breifly and it will play a tune--The store salesmen love it when you do this-gets their attention!!
Some advice...
Go to your local hardware store and purchase a set of tools. You can tear apart a machine completely using a decent screwdriver set with torx bits, a socket wrench set and maybe an anti-tamper screwdriver set. (At least, I did with my old FF. I'm not sure what other tools one needs with modern machines, but that's a start!)
Then go onto Kijiji and find very low cost or free machines. Maybe a used appliance place might have something you can tear down for parts.
Then just go to town. That's how I learned. Don't worry about breaking anything. It's easier to tear the machine down than it is to put it back together, which you probably won't anyway.
There are service manuals on the net that show how to tear the whole thing down and put it back together, step by step. You know you are doing things right when you can put it back together, not end up with any extra screws and it works.
There are also really good youtube videos online that show how to do a trunion bearing replacement for Whirlpool and GE washers. They literally have to take the entire machine apart in order to get at it.
There are massive amounts of youtube videos out there that show all of the basic concepts you need to know. Although, nothing beats getting ones hands dirty!

Slowdown folks, we are dealing with a young man here and we need to take our time to show him the rope!
This maybe his first major message board participation that he has joined and it takes time to learn and understand how it works...
Some message boards are complex or inefficient with data that makes even me go crazy, take a moment and remember how we all got started!
I've seen a recent Hozzer (THS/GardenWeb) thread who was former member of this site who is still bitter from what happened in the past wrote a nasty gram about AW.org..
What enter the internet, stays on the internet for life and viewed by millions.
Thinks about it?!

spinning the drum
Does the drive motor inside the machine create voltage when I spin the drum, which may cause the machine to turn on, or does it stay off like other brands like whirlpool?

spinning the drum on a late DD GE...
I spun the drum briskly on my 2012 Chinese made 24"direct drive GE and nothing happened-have heard many times LG DD s will light some of the indicators if spun.

been there, done that
I have done it before, but wasn't sure if it would turn the machine on.

What happens on my Fisher & Paykel direct drive topload washer is this:
1) If there's a load running and a power failure occurs during spin, the motor will generate enough power to keep the electronics on and the lid lock engaged for safety purposes until it coasts to a stop. Then the machine turns off and remains off until power returns and the cycle resumes where it stopped.
2) If there's a load running and a power failure occurs during any operation other than spin, the machine simply stops and remains off until power returns and the cycle resumes where it stopped.
3) Rotating the drum by hand when the machine is off does not cause the controls to turn on, but if rotated fast enough the motor may energize into a braking mode.
This was a few years ago when I did the drum spin thing in the LG and Samsungs-will have to try it again and see if the design has changed.Spinning the drum doesn't turn the machine on-the motor acts as a generator and breifly powers the electronics until it slows down and is no longer generating electricity..PM motors will become generators when turned.This can make them useful as generators as well as motors.

The LG s still lite up but go off as soon as the drum stops. I do, it at Home Depot to show the customers as the salesmen watch in amazement. If you go to Facebook, I have still photos of the disassembled 2277 Steam model. I had to replace the barings,tub seal,inner tub,outer casings and pump. I found it in a trash heap free. I sold it for $750.00
Yes,like the floor nozzle of a Kirby-a simple electric generator.The brushroll has a small magnet that goes past a coil of wire connected to a LED.When the brushroll spins at the right speed-the LED gets enough voltage to light.

There are some videos on Youtube
Where they use a F&P top load drum and motor as a waterfall generator.
Electric motors are just generators in reverse. It's a way of transmitting the mechanical energy converting it to electric energy and converting it back to mechanical energy. (whew, I'm glad I was awake that day in Physical Science class).

circulation pumps and drive motor operation
I could've sworn that there are models with circulation. How does the motor know when to turn in the opposite direction? Example: cotton/normal operation. How does the machine know when to turn on the circulation pump?
