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. |

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. |

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. |

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. |
