Reading Panasonic/kenmore Motor numbers?

[blackheart]

Bought a Kenmore upright which has a burnt out/burning out Field coil and I've not found another motor with exactly the same code on it and I wanted to check, are the letters at the back just a production date code or something? I have found a few UDS1201's with other letters behind it and I'm just not sure if they'd be compatible? One of the ones I was looking at ended in SXDAB would that work for this unit?

I think if the exterior size and shape are the same another one of these Panasonic motors will be fine. Was that one single fan or two? They came both ways.

Getting the fan housing back on those is an unholy sob too : /

Well that a part of the problem the available ones are ebay finds so I can't really compare them side by side to find out. It was a single fan.
Yes I know, I've done a few of them.

They use these UDS motors in Henrys too.

I think only Panasonic knows what these model codes mean.

Huskyvacs - Numatic & Henry vacuums USED to use Panasonic motors. That was from late 90's to about 2010 or so. Then in the last 15 years, they switched to Ametek Italia 4.3" diameter single stage motors in the Henry canisters. The exception being the Henry & Hetty HVR200 canisters, those use a double stage 5.7" diameter Ametek Italia motor. And I do believe the Numatic commercial canisters may also use the double stage motor too, but not absolutely certain on that.

Those Panasonic motors, while powerful, are NOT very high quality or long lasting - it's very common to see the bearings gone in them around 7 or 8 years. And they are non-serviceable motors. If you had a vacuum with a blown Panasonic motor, this would definitely be a reason to put a different brand motor in it!

As a side note, the double stage Ametek Italia motor makes a perfect TriStar/Airstorm/Patriot replacement motor. It's exactly the same dimensions as the Ametek 116311 double stage motor, but a bit more powerful at 100" waterlift. I used one to give my Vita Vac a bit of a performance boost and it definitely was what it needed LOL!
