Purpose of that "tumbling" as you call it is to distribute and balance load before spinning.
Older front loaders accompolished this using various methods; today's washers however largely rely upon feedback from electronically (computer) controlled motors, drum movements and a few other bits. Mostly or all mechanical driven front loaders required robust and substantial suspension systems (hence Miele's famous cast iron cradle) to cope with various degrees of unbalanced loads. Those machines would spin often even if it meant bashing themselves to death. No one makes machines like that anymore IIRC. By controlling drum movements and other factors machine can sense when load is balanced within set parameters for smooth spinning. If machine senses load isn't properly balanced spin will aborted and it will try another round of tumbles/distributing etc.... then try again. Take a badly knotted or wadded up bit of wet laundry, have washer go at once into a spin and you've a recipe for badly damaging washer. Don't try this at home folks...... Or this! |

As far as modern FL machines go, I think my Maytag Neptune is about as close as you can get to an instantaneous spin. Only with the heaviest, seriously unbalanced loads has it taken a bit of extra tumbling before launching into spin mode. I really appreciate the Neptune's no-nonsense approach.
Besides Maytag's unique (to me, at least) balancing/counterweight system, could tilted tubs simply be better at balancing than perfectly horizontal ones such as our 2008 Affinity FL, which couldn't balance its way out of a paper bag? More than once that machine just gave up and issued the end of cycle signal without any spin at all. |

The thing I like about Neptune is that it has three unbalance switches.
In a timer machine these switches could be such that if any one of them activates (opens) a normally closed micro switch it will cause a relay coil to insert itself in series with the motor's wingdings causing it hold open the normally closed low impedance path for the motor to function. That means upon entering an unbalanced spin, the spin motor will simply cease to function allowing the cycle to progress. When to motor contacts open the scheme resets itself for the next time the machine goes into spin. I'm well aware that is not how the Neptunes were wired, but how I would have wired the Neptunes.

will do that to distribute the load and aid in dirty soapy water removal as it slowly gains speed steadily. |

I'd love to know why balance rings are disappearing on the market for front loaders across all brands. Whirlpool now lacks them on all but the highest trims, and I've noticed they're missing on many LG models as well. It seems to me that balance rings are such a simple yet essential part of vibration reduction, especially with today's high speed spins, why now are we seeming to go backwards? Some of the recent videos available for several newer FLs are cringing to watch because of how they'll rip into full speed while the drum itself looks to be terribly off balance. I can't imagine that being good for the bearings.
The WFW92 front load I have is still going 3+ years strong and does a mostly fantastic job balancing and spinning with barely any movement in the drum rim, if at all. Only occasionally will a spin seem off balance but it quickly aborts and redistributes. It's fascinating to watch the distribution behavior with how it adjusts the drum speed ever so slightly to shift the clothes around without going back down to a full tumble, and once it decides the ball-bearing balancers can handle any weight offset, it takes off almost like that video IowaBear posted above. The drum gyrates for a few seconds until the balancers shift and suddenly it's perfectly smooth. Balance rings really changed the game for both top and front loaders but maybe in this era we live in, no one cares enough to know whether the machine has it and the companies capitalize on this by cutting the cost for the components. |

That is interesting. I did not know balance rings were disappearing. Maybe to keep shipping weight or cost down? But hey, it proves to others that regression can be legit or a good thing.
Regarding the two Malleys, interesting! Though you've still got to bolt it down. I never liked the transmission and clutches on older FL machines. Or the lack of reversing tumble. Do you have pics of this machine or its internals? |

Here you go. This is the motor and drive layout. No gearbox, just the overdrive unit |
