We've tried to caputure the very "energetic" Frigdaire Pulsamatic Washer on video before but because of frame rates it always looked like the agitator was standing nearly still. Well will my new digital hard drive video camera it appears it has no problem capturing the Pulsamatic in action if you record it in very high resolution!!! Here are two video (they are exactly the same) one in high res the other in medium res (for dial-up modem users)

The Pulsamatic in High Res 22mb for Cable/DLS users

The Pulsamatic in Medium Res 8mb for slower dial-up connections.

Thats FANTASTIC Robert!!!!

What a fab wash action.

Its really great you can now film it.Am very impressed with the camera.

A real treat indeed sir.

Thank you very much!

Robert, AWESOME video! Glad you could finally capture the "energized water" on camera...lots of vubulations with this machine as well!

I'm glad I was able to play with this machine at the Convention and experience the Pulsamatic in person; there's really nothing quite like it! I brought my old VHS-C camcorder last year and had no problem getting it on video since the frame rate is rather high for analog, IMHO. However, in Tucson I brought a new Sony mini-DVD digital camcorder, and I know the frame rate was considerably slower because some of the spin cycles had that "warp-speed" look to them.

Wow, I remeber seeing this on someones webpage, and it looked like it was vibrating rather than pulsating up and down.
 
question?

great vid robert, thanks, is that the same "tranny" as the regular unimatic ? oil-filled tranny? but just engineered/designed for a faster and shorter stroke ? why didn't they stick with that mechanism ? seems like it turns over VERY well yet would not tangle or roll sheets as badly or quickly as a regular unimatic would ... basically I am curious as to how each tranny differs
 
Wonderful video

Thanks for this video, what a great wash action! I loved watching the water grow murkier as the soil was gradually and very effectively being removed over the duration of the wash.

Great video Robert! I can recall watching this machine at Greg's house. Brings back lots of good memories!
 
Thanks, Robert. Which Pulsamatic do you feel performs better, this one with a 3 Ring agitator and the rubber "Energy Ring" or the earlier one with the solid black Bakelite agitator? I would not want to dry that load in a Filtrator after the slow spin of the Pulsamatic. Why do you suppose Frigidaire emphasized the longer stroke trannies over this one when the later ones were modified Pulsamatics, right? I think that the engineers had too much money to play around with.
 
The Pulsamatic mechanism evolved into the Multimatic mechanism. This mechanism was GM's way to try to produce a less expensive machine. The Pulsa/Multimatic transmission is belt-driven and designed to be fixed while still in the home, while the Unimatic was direct drive and usually needed to be removed to a shop to be repaired. Both are oil filled. I beleive the evolved Multimatic allowed better multi-speed use than the Unimatic.

I think the Pulsamatics are by far the most interesting and captivating machines to watch. Thanks for the video, Robert!

Greg, it’s not a Unimatic transmission it’s a Pulsamatic Transmission, it looks very similar to a Mutlimatic, but only one belt and no clutch. I have almost no tangling in my Three-Ring agitator Unimatic when I take an extra moment to load it properly, but with the Pulsamatic even with properly loading it can tangle more. But really tangling can be eliminated by proper sorting and loading. What you really have to be careful with is not to wash all long sleeve shirts together in on wash load, I just sort and mix other things together. Sheets need to be picked up from the center and loaded into two sections of the washtub, intermixed with the pillowcases. Really the only Frigidaire washer I have found that is difficult to stop the tangling in is the 1947 Frigidaire and that's because of the bowl shape in the wash tub that they changed in 1950. Even consumer reports said in 1958 "Special care required in loading to avoid tangling". Obviously the people at CU figured out how to prevent tangling or they would not have been so kind.

Which Pulsamatic do you feel performs better, this one with a 3 Ring agitator and the rubber "Energy Ring" or the earlier one with the solid black Bakelite agitator.

Hi Tom, I don't know what you mean by the solid black Bakelite agitator, the earlier Pulsamatic agitator had a rubber pulsator as well, but the upper section was black bakelite. I think the '57 performs a bit better with the redesigned wash tub, but I find there really is very little difference.
 
Unfortunately Jeff that's one of the drawbacks, I think the spin is only in the 600s range, as compared to 1140 for the Unimatic. The wash action is sure fun to watch though!

Oh Bob A....
 
Laundry harmonics

It would be interesting to have that video looked at by a physicist. The continuous "bumps" of water on the surface of the load indicate that there might be a lot more going on in that washbasket than simple "turnover". I wonder if the cleaning ability of the Pulsmatic wasn't augmented by some low-level sonic wave activity. Pity that the spin speed wasn't anywhere near as vigorous and the wash action.
 
Hi Jeff, the pulsamatic pulsates and spins at the exact same rate, 630ppm and 630rpm respectively.

Consumer Reports nor Consumer Research Bulletin never tested a Pulsamatic as far as I ever found.

It is a very fun machine to watch to say the least and after the White Perforated Double Tub early Unimatic its the next most rare Frigidaire washer.
 
Who all has Pulsamatics?
me (not working)
Robert
Don Haggarty
Somebody Down Under has the semi-automatic one

Greg M? Jetcone? Tomturbomatic?
 
very cool...

That pulsator is smaller too than the Unimatic's right?
Thats a belt drive mechanism too?
 
Peter I think there are three surviving models in the USA and two in Australia if I remember correctly.

Jeff the rubber Pulsator is the exact same size between the Unimatic and Pulsamatic (same part number), but the plastic agitator column above the rubber pulsator is slighly smaller on the Pulsamatic.
 
Who has the surviving ones??

Hi Peter and Robert,

Robert is correct: Nathan (Brisnat81)has the semi automatic version and somebody in Victoria has a fully automatic one: i was outbid on it from ebay a few months ago...see the attached pic.
