I was doing some research on motor maintenance (see the other thread I started with questions) and ran into this video. It compares the Amatek Lamb motor to a Mytee. Both work well, the Mytee pulls more on the waterlift test and is quieter. It uses a few amps more power, though.

I couldn't find much at all on the forum about the Mytee. Does anyone know anything about it?

I think this is the same motor on ebay. I'm very curious if these are a good, long-lasting replacement motor for the Amatek Lamb. Curious.

The shape of the fancase is the same as my 240v chinese Ametek clone motors that I have in the Tristar and Project BarrelVac, so I'm not entirely sure they "invented it" themselves, and are just peddling chinese clone motors under their own brand name...

And not to mention, the name "MyTee" sounds like a name for a company that makes custom-printed T-Shirts, and just googling the name, there IS a T-shirt company called MyTee(Spot)!!! :P

Hi sanifan,

Have you checked out the company website?

Well, Mytee seem to be a company with some history. So that's reassuring.

I doubt they build their own motors, however. I tend to agree with twocvbloke that they probably outsource them. Whether the specs on the motor are prorpietary and commissioned by Mytee, I don't know. I'd imagine they're sourced from China, it makes the most economic sense, but again I don't know.

Now I'm hesitant to think the a product is necessarily inferior just because it is made in China. Sure, there's a lot of low quality dreck made there, but there are good quality products made there too. I guess it comes down to the standards the manufacturer demands from Chinese made OEM parts.

Having said that, what do you guys think about Chinese made replacement motors for vacs? Do they work well and last long? If so, are there makers that known for their quality? I'm interested in the Mytee because of the increased water lift specs over the Ametek. Now that I think about it, it may not be a drop in replacement for the Tristar CXL as it's a bit bigger.

I'm hesitant to buy a generic motor without knowing its track record, no matter where it's made. In fact, I just purchased a Lamb Ametek to replace that in my CXL. It costs more than generic, but I'd rather not risk my motor pooping out in a few years. The Lamb Ametek, as we know, is proven. I'm still interested in more powerful motors, though, as long as they're known to last.

The chinese clone motor I have in my Tristar has done well to date, it's got plenty power and doesn't have any unusual or annoying noises, it does run a bit on the warm side, but I tend to thing of that as a positive as the house gets a bit cold downstairs so it's like having a mobile space heater while I vacuum... :P

It's meant to be a drop-in replacement for more recent Numatic vacs, and wasn't a perfect fit in the Tristar as the gasket was made for motors with that round but ont he back of the fancase, which the clone does not, and as a result, the motor actually forced itself out of the gasket when I was testing for leaks (hand over the hose port, then suddenly releasing, the pressure rapidly built up behind the motor and POP, it fell out into the bag chamber!!), so I just used a bit of silicone sealant to glue the motor in place and it's been there ever since... :)

I don't expect it last as long as a genuine Ametek-Lamb motor at all though, nothing that comes out of the PRC lasts as long as the originals that they have copied, they just cheapen everything to make more profit, hence why us westerners are poor and they're rolling in the reddies... :S

The way of the world...

"...they just cheapen everything to make more profit."

That happens everywhere these days, doesn't it? Not just in China.

Witness: Chips Ahoy cookies from when I was a kid. They are one-third the size these days! And they don't give you any more cookies!

As far as motors go, I don't mind tinkering as long as the replacement offers some increased performance or is significantly cheaper. These days, though, I tend to go with the proven thing. I don't have the time or mind space these days to worry about unexpected problems should they come up.

I'm sure you'll get good use out of that motor. Unless something is really a dog, it seems like you should get good perfomance.

I owned a carpet cleaning company that my dad bought from me when he  retired, We have 10 Mytee extractors. They are amoungst the best portable cleaners out there. while the lamb motors were good the ytee ones are the best. Not one motor has burnt out in the 4 years since the machines were bought. we own the mytee speedsters. 

 

There designs are well thought out and easy to use. My dad uses them in conjunction with his truck mount extractor.

 

I may be a Proud South African born Brit but no one can build industrial carpet cleaners like the USA no one. stuff out of the Uk and Eu is just to domestic. The USA made extractors clean the best and last the longest and are the most reliable.

Gareth, your opinion carries a lot of weight with me as I know you have a lot of engineering and practical experience in the vacuum industry. So I'll take it that Mytee products are good.

It may be a stretch to assume that all of their motors are good just based on the performance of your specific machines, but I take it as a good sign. It's hard to tell how a company specifies OEM parts from one model to another.

Do you know the specifics of Mytee motors? Specifically if they are made in the US? Not knowing anything about the company I would just assume they outsourced their motors. That would be my initial thought. Again, I know nothing about the company.

If the motors are good, then I am very interested in seeing which Mytee motor will be a drop-in replacement for my Tristar CXL. The test on YouTube doesn't tell me much about compatibility. Looking around the web it seems very difficult to tell what is compatible with what unless you have a manual for cross-referencing motors (like they have with batteries).

The video compares the Mytee 5.7 to a Ametek 6.6. If I'm correct, the motor in the Tristar CXL is a 5.7 inch Lamb Ametek (I forget the model number off the top of my head). So the Ametek in the test isn't that used in the CXL. If the CXL uses a 5.7 inch Ametek motor, do you think this Mytee 5.7 is drop-in replacement? Again, it is hard to tell without a cross-referencing guide. How would one find out?

Ametek model number...

I believe the Lamb Ametek used in the CXL is model number 116311-01.

Interestingly, the specs says this particular motor tops out at 95 CFM. Interesting, as a lot's been said of the CXL's great airflow, and 95 CFM doesn't seem that great compared to many other vacuums out there (my Sanitaire Mighty Mite canister, for example, is specced at 140 CFM, and my Sanitaire upright pulls 145 CFM). Confused.

...and here's an even lower price on it.

"They are one-third the size these days!"

THat could also be because of nanny state rules, anything that makes people fat must be made smaller, but taxed more and priced higher... :P

That and everything we saw as kids always seemed bigger when we were little... :P

Anyway, the biggest differences between those motors and my two motors is that my two are 240v, and have tapered fins up front, rather than flat fins like those Ameteks, which increases the suction power, and coupled with the already impressive airflow (though I haven't a clue what it is), it makes for a pretty powerful vacuum cleaner, more powerful than it was before it went for a flight over the atlantic... :)

And the voltage has little to do with the performance, unless it was on a variac and being turned up & down to raise or lower the voltage... :P

Well, from what I can see, the Mytee motors seem to be made for commercial extractors. It makes sense: Mytee designs and sells extractors, not vacuum cleaners. So the question of a replacement motor for the Tristar may be moot. I'm tempted to call the company to check, though.

Hi Sanifan 

 

Thank you for the compliment.

I am not sure were the mytee motors in my machines are made but each machine has 2 x 3 stage tangential motors, hooked upp in air parallel  to give greater cfm. 3 stage meaning they have 3 fans and tangential meaning it is a side discharge for exhaust air
