project - Lamb motor upgrade for Electrolux 2100 series

[blknblu]

So far, so good


 


Retrofitting an Ametek Lamb motor - 2-stage, 5.7 inch, double ball bearing into a 2100 series Electrolux


 


Tested the motor (used motor with low usage), runs much stronger than original 2100 series motor


motor is roughly the same size as the old one


 


tapped Lamb mounting holes for 10/32 screws


Modified original motor mounting plate to accept Lamb motor


(note, next time I will duplicate the Electrolux holes onto the Lamb motor, the Electrolux plate is fragile)


I added some metal tabs, and some washers to secure the motor.


 


Modified finger guard and mounted it to motor & plate


tested plastic motor cover for fitment


tested motor placement in a spare vacuum housing


Waiting for thermal fuse to come (thermistor), Lamb motor does not come with one.


Figure out which vacuum to upgrade


Got the motor cheap, brushes are like new - did I mention it is double ball bearing


 


Specs for this motor:


Motor Type: Thru Flow


Discharge: Peripheral


Bearings: Double Ball Bearing


Sealed Vacuum: 91.2 inches


Maximum Air Watts: 245


Maximum Air Flow: 95 CFM


Maximum Amp’s: 8.3


Motor Speed: 18,390 RPM

Great work!

There are Lamb motors of higher amps and more CFM that will also fit in the 2100 series.

I once took a 2 stage Lamb motor out of a Kenmore Whispertone and put it in a 2100 series. I made the horrific mistake of letting the wire harness come loose from the inside of the top half. It took forever for me to reconnect the wires correctly because I didn't have a diagram. One I had it up and running it was a beast! Also, if you ever get a hold of a Rennaissance style canister that you'd like to play with, you can chip away at the plastic around the motor fitting on inside of the bottom half of the body and the 2 stage Lamb will fit snugly in this also. I actually used the cutting blade on my Dremel to do this and then filled in the gap around the motor with spray foam insulation. It was a totally different machine afterwards.

Thanks, I did not want to go higher with the amps. Keeping it roughly the same.


All wires will be zip tied and tidied up, no worries there.


 


Never saw a Renaissance motor before.


Found a thread with a pic though

All set, had to make a couple of mods to get it all back together


sound is similar to original, suction is slightly better


For me, it turned out cheaper than the prevalent Electro Motor upgrade for the 2100 series. (I got the Ametek Lamb motor cheap)


I purchased a new thermal fuse, and a dense foam gasket for the motor.
