Ametek 116765 Lamb Central Vacuum Motor

Direct replacment for my Electrolux in house vacuum.Fired right up after replacing the motor and we put many hours on it without issues.

Used this to replace the motor on my CentralVac which burnt from running for too long. Replacement was pretty simple and just works. Seems it is a little quieter than the old one I replaced it which is an added plus

I was concerned I would not be able to switch out this central vacuum motor. It ended up being a lot easier than expected. There were 3 spring nuts to hold down the motor and 2 wired to connect. Works great!

The motor was ordered to fit a 20 year old Beam Central Vacuum. The motor fit as it should. Did need a couple of small adjustments; original motor had a screw hole to attach the muffler to the motor, this one did not and we had to drill for new one; the second is that the motor did not come with wire lugs, did have to do a small bit of soldering to get the right ends to connect. Not of it was a big deal but it was not just swap. Motor works like it should and vacuum is running fine. Good deal on Amazon. Would purchase again.

Works really well for two years now. My central vac is used multiple times a day 7 days a week with no problems.

It's a direct replacement for the 20+ year old central vac motor.

Motor sounded louder than the original (high-pitch screechy, like something wrong with bearings) even when it was brand new. It failed completely after about one month of ordinary use (10-15 minutes every couple days). When it failed, it got even louder, but lower pitch, provides little suction and smells very bad, like hot/overheating electrical equipment. Likely some kind of bearing failure. Quality == FAIL.

This vacuum blower *really* moves the air. The three stages really allow it to produce a great vacuum - I measured nearly 10" mercury (that's more than 125 inches water column) with a blocked inlet, which is the mode I'm using it in (for a special type of vacuum press).Because of my application, I needed the separate bypass cooling air that this blower uses. If you build your own enclosure, be aware that it's essential to significantly separate the cooling fan inlet (on the top of the motor) from the discharge (all around the base of the motor). Even when the inlet is blocked, so it's theoretically not compressing any air, it still consumes nearly a full kilowatt (~960 watts, according to my clamp-on ammeter), and all of that ends up as heat, of course. I actually had to add a close-fitting baffle to keep the exhaust air from recirculating back to the inlet.Be aware that all that energetic air thrashing, as well as the compression (Boyle's gas law, etc.), really causes the process exhaust temperature to rise, too. I measured nearly 200 degrees there, so plan your discharge accordingly.With these caveats in mind, if you need a blower that moves a lot of air, and has quite a high head pressure (I didn't measure the stopped exhaust, but I'd expect around 5 PSI or so), this is an excellent choice, especially for the price.
