Hey guys, what are the similarities between the fisher&paykel &lg washer pancake motors? To me, both generate electricity when you turn and spin them. They seem large compared to the whirlpool vmw motors.

Nothing much in common with VMV motors
I think you mean the VMV belt drives. VMV motors are (I think) brushless, reversing, capacitor start, but do not have the same type of rotor or stator windings. First gen. Cabrio 4.5 cu. ft., and Bravos XL machines are very similar to the F&P type. I've read here that Whirlpool licensed the design to use from them. Not sure if thats accurate or not. I have ho scale Marklin locomotives with a C sinus hall sensor motor. Quieter and smoother than the previous 3 and 5 pole high efficiency skew woound armature, but costly to make. Required a pcb driver board. They also were interfering with the digital MFX r.f.i.d. signal so they discontinued it. I've not experienced any problems thus far. First and second gen. digital was Motorola format, then MM2 (Marklin Motorola)
They've gone with can style sealed 5 pole motors as the other makers use now. It gives them more design flexability at lower cost. They've also homoligated their digital decoders to be compatible with other brands, including DCC, not only their a/c 3 rail system. Modleers now have more options with brands. Piko, Roco, Fleischman, HAG, Acme, LS, Faulgrex, and Lemaco, that brand at a very high price point. Also are not only bound to use a Marklin MS2, CS2,3, or 3 plus controller, but can opt for the ESU Ecos2, Viesmann, or other.

lg dd motor
How many poles do the lg washer direct drive motors have? I've noticed that when you spin the tub, electricity is generated. How many magnets and coils does it have? I've heard they're very powerful.

F&P developed the SmartDrive motor and introduced it on their toploaders in the 1990s. DishDrawers use a mini version of it.
Whirlpool partnered with F&P to use the design (including the floating basket) on the original Oasis, Cabrio, and Bravos washers. For anyone not aware, there were both agitator and impeller models ... although the WP agitator design was more of an agi-peller than the more-traditional agitator that F&P employs.
Original and current VMW belt-drive design uses a completely different motor, not SmartDrive.
WP redesigned with a mode shifter to eliminate the floating basket but still use the SmartDrive motor on some higher-end models, which is known as VMAX.
Several manufacturers (WP, Samsung, LG, maybe others) also now use the SmartDrive type of motor on frontloaders.
F&P changed the number of poles & magnets, material design (copper windings vs. aluminum windings) and the operating voltage of SmartDrive several times through production. Motor control boards are not cross-compatible among the progression of revisions. WP and other manufacturers may or may not follow the same progression of revisions.
Both the rotor and stator on my F&P AquaSmart (serial June 2009, which also indicates assembly in the factory F&P had in Ohio at that time, maybe shared with WP) are stamped with "Whirlpool" and a WP part number.
Pics below for you, Jerome. You can count the magnets and poles on this version. There are four poles under the RPS.
This is the stator and an external pic of the rotor on a 2011 Samsung frontloader that I repaired in 2016. I don't have a photo of inside of the stator to show the magnets.

Also, I can hear a high pitch noise from my Kenmore/lg washer. I imagine it uses high current. Maybe lg uses 42 poles.

They do hum
rather noticably. Also, if there is a thyristor on the sensor curcuits, they can emit harmonics. Locomotive traction motors use thyristor gate controls, etc. The Siemens Taurus plays do re mi fa so la ti do as it accelerates from a stop the first few yards or so.

The VMW motor is an induction motor-cap start.No magnets in it.Now-if you feed a LV dc into the start winding and turn the motor with another one or an engine-then you have an induction generator.
Of course the PM washer motors-and some ceiling fan motors were made with PM rotors-simply spin the motor and its a generator-Or its a dual way transducer-motor or generator.Several times at Best Buy have given the LG or Samsung washer drum a good healthy spin-the dials light and the machine plays a tune!The salesmen don't like this.Try it-FUN!

Oooh that does sound like fun.
I'm off to civilization tomorrow, I'll have to stop in at The Good Guys and see if it works on their 240 volt models.

F&P uses the power generation effect of SmartDrive to keep the electronics and lid lock powered until the basket stops if a power failure occurs during spin.
my first experience
My first experience was with my mom's lg front loader. When I would spin the drum fast enough, the machine would turn on and the chime went off. It literally scared me. I didn't expect it to turn on. Luckily, I turned it off by simply pressing the power button. It was roughly a month or two after when I got familiar with the machine in approximately early 2008.

I noticed that when I was trying to figure out why the ul code kept popping up. I was spinning the drum unplugged and it started lighting up.
Later I found out the motor bolt underneath was loose and tightened it up and all better. I have a Kenmore/Whirlpool 700 series washer here.
