Vacuum Cleaners Discussions

Did anyone notice that the DC11 is back on some of the Dyson websites... Here's one that I thought was gone forever...

Here's a better pic:

Hello Trilobite:

Thanks for the DDM motor schematics.  Very interesting. 

Your pictures pigued my interest.  I checked the official dyson specs of the canisters on the dyson UK web site.  Interesting results.  Dyson's 5 year old DC11 with an encore presentation has 275 air watts.  Newest dyson DC19 T2 cann has 280 air watts.  DDM DC22 has 200 air watts.  200?  That's a far cry from full size power.   I'm even suspect of the nice even 200 number.  Does the DDM motor actually deliver suction power equivalent to industry standard vacuum motors?  Especially at the exorbitant price.  The reason for the smallish 7 inch rug nozzle on the DC22 may be the lesser suction power and not the maneuverability in tight spaces.

Hello retardturtle1:

You may know this already so forgive me if I'm being redundant.  The pano motor that Severus speaks about which is installed in dyson's DC07 uprights is a one fan reversed wired pano motor that has been in the US vacuum industry since the early 70's.   Good motor but standard issue.  Not the TOL tri-force pano motor that's used in the TOL pano uprights and canisters.

I don't know what components and in what quantity are in the DDM.  Interestingly, dyson went from one of the least expensive industry sourced standard issue motors for its first upright launch in the USA to a sophisticated esoteric non-standard vacuum industry motor for the DDM.   The timing couldn't be worse in light of the global recession especially in the USA where dyson at one time boasted two thirds of its vacuum market sales.

HI CARMINE

nothing to forgive...thats  what the forums all about..Q&A, ...ideas..learning ..fun stuff....anyway, i knew the 7 had a pan motor...but why rev wired...? and i have no clue abt where the other motors are from..but i think the DDM was in one of  his earlier cans .[not sure]..guess the timing is bad at the moment for a chunk of change on a vac... that is an  intresting  looking motor tho...i never seen a motor like that. so whats your take on it ?

TRIBOLITE...

Yes ,,thank you for the all the info  and i do find it to be an intresting design....but as CARMINE said...200 a/w is ALOT lower than 280...not seeing where this motor is supirior over all the rest...or how it can overcome a 40% a/w loss..

That is only 29% loss.

Carmine failed to mention the UK DC22 uses a carbon brush motor.  The U.S. DC22 uses a DDM...  88,000 rpm, pulls the Baird meter to 10 and sustains this for 4 - 7 years.

I first went to the Japanese dyson site but unfortunately I can't read Japanese.  The dyson UK was the best alternative.  If you know the air watts for the DDM DC22 post them for all of us to know and judge.

I have a HOOVER China sourced cann with a cord winder purchased in August 2007 that I've used for almost going on 2 years now in a couple months.  It's smaller than the DDM DC22 and has full sized suction power with a full size rug/floor brush.  It cost $50.

DIB:   To date there is no US DDM DC 22.  Not on the USA dyson site.  If retailers have it, I haven't seen it and don't know if it is the UK carbon brush motor [that you speak of] and/or the Japanese DDM, which as was mentioned by retardturtle1 the rights may have been sold by James to the Japanese market exclusively.  I went to the Japanese site but couldn't make out the specs and costs.  Do you read Japanese?  Maybe you can assist here and provide some insight with the issues?

HS:

Using 'only' with 29.58 percent is logically inconsistent.  1/3 loss/gain of a motor's suction power is not ONLY, unless you are using sarcasm.  1/3 of something/anything is a substantial amount/percentage.  I keep telling you:  Take off those rose colored dyson glasses.
