From what I can tell there were 3 variations/iterations of the motors in the Electrolux 1205.   At least that's what I discovered looking through this forum.  

 

Also, looking for armatures was interesting, I found what looks like three different motor armatures for the 1205 motor.  There is a long shaft and short shaft version, and in the short shaft version there appears to be two slightly different shafts.  

 

I have this particular motor apart.  All I know is the previous owner said it was an Electrolux 1205 motor, and it had some masking tape on the fan housing with the hand written :  U-139 (no idea if this was an inventory ID or part of this motors part number)

 

Other then "Electrolux" stamped on the top of the motor, there is only one other marketing.  When I removed the fan blades, inside the circular ring is stamped 6710-47 (interesting note the 47 is stamped upside down?) which probably is just casting mark for the motor housing.  Pictures below

I thought this video on YouTube was excellent.

It demonstrates how you can test your motor armature to see if you have a problem.  I know this has been discussed in great detail in several threads, by knowledgeable members.  But I'm a visual learner.  So seeing it done really helps me.  Since I'm rebuilding this 1205 motor as a learning process I thought I'd post that here as well.

So there is never a good reason to throw away a motor.

I got this old Electrolux 1205 motor for an education.  And an education is what I've got.  I have the motor disassembled and I am currently refurbishing it. 

 

Refurbishing an electric motor is not only possible, it's not really that difficult.  For those of you with antique electric motors instead of replacing them with Chinese manufactured motors you can rebuild them yourself. 

 

Is this something this forum is interested in seeing? Rewinding armatures, fixing motor shorts and replacing bearings is not that difficult. 

 

On this 1205 I intend to replace the final fan bearing, possibly with a ceramic bearing.  Which should make this around 50 year old vacuum motor go for another 50 years. 

 

I don't think there are many engineers on this forum, or people who are interested in electric motors and how easy they are to restore.  But I'll update this thread just in case someone in the future doesn't want to update their appliance with a Chinese communist made motor.  

   

I expect to bench test this 1205 motor sometime over the next week or two.
