air comp motor?

69.5CUDA

Blah Blah Blah
so..my beast went up in smoke..there are litteraly molten copper bits in the bottom of the motor.....

this is the unit on there MC022387IP

....and yeah the comp is a CH

lets face it tho..that CH branded motor is just branded CH and not made by them..its likely made by baldor or some other company

to the point..i need a "good" replacement at a FAIR price..im in no mood to pay for a "name"..and the mounting is unimportant as the comp has multiple mountings built into the deck...

anyone know what to grab..what to stay away from etc etc etc


EDIT
after opening it up...it looks like a centry AO smith motor...yeah...the cheep bastards

oh and specs
HP-5, Hz 60, Volt 230, Amps 22, RPM 3450..7/8 flat keyway output shaft

Baldor isn't too bad, for the low cost end of things. Unless you're really working the compressor Baldor should hold up for a good bit. Capacitor start if the pump is old...

My body shop compressor motor died a year before we closed and I upgraded to an industrial unit (which should have been on the compressor from new considering the initial cost). Can't for the life of me remember the brand name though... It was just under $1000 CDN, which would have been something like $211 US... ;)
 
well the old unit is a 4 cap!?!?!?....a CH "re-branded" motor is 500$..a centry/AO is about 250-300...still hunting to see if i can even find a non 3ph 5hp baldor
 
The capacitors let them get away with under powered motors. Four caps tells me it really was a POS motor...
 
thats kinda what i assumed...a lil digging and it seems the 4 cap was the "upgraded/updated" motor ....sad..really bloody sad..goes to show you "name brand" doesnt mean anything
 
heres what ive found so far..if anyones got an opinion

weg(more hp means working less as hard right?)

biggest issue im finding is finding anything that size in single phase is a pain...everything at 5hp jumps to 3phase

Absolutely untrue.

If something is cheap, it's cheap - does not matter what brand name is on it.

Many manufacturers make "entry level" and "premium" lines to satisfy multiple markets. Precious few make only high - end goods....there is no way people like you (or me in the case of things like an air compressor) will spend the extra money, and people like you far outnumber those who want/can afford premium quality.

So while "Sony" is not a guarantee of better quality, the fact is that if you as a consumer do a little research, you can buy a better quality TV from Sony, than say the Wal*Mart or Costco house brands offer.

I assume by "CH," that you mean Campbell-Hausfeld. That is not a brand I would necessarily associate with premium quality. They may make some good stuff, but it seems to me that the bulk of their stuff is made for the Home-Depot/Canadian Tire low-end consumer market.

I suspect that the 4 caps may also be there because an oversized single phase motor requires more "juice" to get started than a similar sized three phase motor.

...but that's not entirely true either... A lot of manufacturers source out their econo product lines to other manufacturers to keep cost layout to a minimum. Not always the case, but that pricey Sony product may be from Sony's actual production line. The cheaper Sony may be from LG or something similar, just rebranded to fit Sony's low-price point.
Store brand is usually low-price point, even if it is made by better-name manufacturers. My ex-business partner's uncle was a rep for Lincoln welding for years. According to him, the Lincoln stuff you can buy from places like H-D or Crappy Tire might carry the same part # as what you can buy from Lincoln, but the machines have been lightened up considerably to ensure places like H-D could buy them cheap enough to make maximum profits and still undersell the Lincoln depots, which didn't chase the walk-in retail trade like H-D does.


The industrial motor I bought was a 7.5hp 220v single phase... so they are available.

Actually - most of the cheap shit is made by the same Chinese OEM manufacturers, regardless of brand. But that stuff is built to meet a price-point, not a specification.

That's why I said: you can buy good stuff or utter trash with the same brand name on it....and if you think the thing you just bought cheap at Wal*Mart or Home Depot bears any relation to the premium product line, you are kidding yourself. It's simply a matter of survival for manufacturers of consumer goods, who seldom make a go of it providing only high quality - unless it's truly exclusive products marketed to only the wealthy.

Professional goods like those I sell tend to be a little different, because people make their livings with these products, so they need reliability and support....but even that is being over-run by Chinese knock-offs of the real deal. Matter of fact, often complete counterfeits marketed as the real thing.... I get 5 - 10 emails a day from China urging me to buy container loads of this shit for resale.

Yeah - I know you can buy good quality high torque/horsepower single- phase electric motors for industrial applications. But they are rare and they cost big money, and high cost does not sound like what 69.5 is after.
 
Even Snap-On Tools is marketing some stuff made in China now... They do honour the warranty but it's sad to see a premium brand like that diluted because of the need to carry a cheaper line.

Years ago, Mom & Dad were up for a visit. I had just bought a cordless Makita 12v drill. Top of the line... 12v tells you how long ago that was. Dad was checking it out and though he fell in love with it, he was aghast at the price. Months later he calls to tell me he found the exact same drill at a discount store, for a fraction of the cost. "It's the exact same as yours, same colour and everything!"
I still rib him about it. :)

A year or two ago, I got into an online argument with a fella on that other mopar site about this very same thing.
He got downright pissy when I told him that. Guess he didn't want to admit he'd been fooled...
 
My money would go on the Weg.

No arguing, we're both saying the same thing but in different ways...
 
good to know that i was leaning on the right one...time to pull the trigger on it...best deal i could find localy on it was 400$
 
What is the compressor rated at for output?
If it's what I think it is, you could probably find a bigger and better unit for close to that $400.
 
i went digging for used and came up empty handed..short of jumping to about 650+..the biggest issue is finding single phase..im not setup for 3phase...nor do i have the inverter?

i can get that weg shipped for 320 thru amazon

if you know of something good for 400$ish im all ears...the rig ive got is a BEAST..i know i posted when i got it on here but cant find the post ..its a late80 early 90s CH...14.6@135psi/17.3@90psi 80gal model# CIQ71083V

ill toss up some pics..as soon as they upload...cant order a motor till tuesday anyway
 
Just to chime in a little here, on a couple of points:

On the price v. quality issue: My compressor is 100% made in the US, by C-Aire. I did a lot of research before buying it, not wanting to buy a piece of garbage that would fail in 10-12 years or less. A lot of large, air-intensive shops in the area have ancient C-Aire compressors, and none of them have ever had a failure. So I dropped the $700 on mine. That got me a 17-gallon, 1.7HP "portable" unit that can be configured to run on 110V as I have it, or 220V if desired. I used quotes around the word "portable" because unlike the 45-pound, 5HP 22-gallon Craftsman it replaced, this sumbitch weighs 175lbs. It's a bear to move, but it's very quiet and its performance is far beyond anything similarly sized you'll find at Sears, Wal-Mart, Home Depot or anything else. It's a single-stage 2-cylinder, cast-iron pump. When I'm using my sandblast cabinet, it maintains 80PSI no problem, and I'm pretty sure it will outlast me.

Now, the specs on mine bring me to another point, specifically about the motors you're shopping: Are you looking at peak HP ratings, or running HP? Big, big difference. My compressor's puny 1.7HP rating is its running HP. Its peak rating, which is what everyone else slathers across their compressors, is 4HP. Peak power on an electric motor is found at zero RPM (startup). As mentioned above, that's pretty easily manipulated through the use of large capacitors. It's a similar situation to stereo amplifiers, a subject near and dear to those of us whom have dealt with them professionally (help me out here, Nodda :D ). Yes, you can buy a legit 1,000-watt 4-channel amplifier for $200 at Wal-Mart... or, you can shop a vintage PPI amp from the early '90s and spend more on a 50-watt 2-channel amp--used. The Wal-Mart amp is rated at peak watts, which you'll rarely ever see, and the PPI is rated in RMS watts, which is what you'll see in daily use. There's a lot more to both situations than simply the flashy, large ratings numbers given in the advertising information. Rest assured, the PPI amp would blow you out of the car while the Wally World unit will sound like ass at 1/10th its rated peak output. Learn what all the specs mean, then research the ones that really matter. If you can't find all the specs on a given motor, keep shopping. Manufacturers only hide specs when there's a good reason to do so; that Wal-Mart amp isn't bragging loudly about its S/N ratio or THD. The "5HP" motor on my Craftsman compressor was scarcely larger than Stretch's fist; the "1.7HP" motor on my C-Aire is something like 8" in diameter and about a foot long.
 
If you can't find start-up hp like doc said, check the amp draw. It's use the rated number at start.
It's not really a gauge to measure power but the lower the number should give an indication of the quality of the motor. You won't find much of anything with real copper windings anymore, unless you step way up to industrial-quality like I did, but a lower amp draw at start should be telling you what is inside, quality wise.

My industrial replacement 7.5 hp had an amp draw of 22, while the factory unit was a 28 amp pull.

I was given an old Lincoln 220/440 motor when I opened the shop. It was always my intention to use that motor and build a compressor myself. It was used by Bell at the telephone exchange back when the dial tone you heard was actually the sound of electric motors running. The thing weighed a TON! 15 hp and IIRC, 20 amp draw.
I never did get around to doing anything with it. The shaft had been bent at one time so some work was needed and it was a three phase motor so a step up converter would have been required. The thing was a monster!
 
good info..and thanx for that..course as much of it as i understand..i dont turn up many other options for motors..maybe im not looking in the right places?...shrug..ive given myself till monday night to order one up..as i allready pushed back a job and the other is having to linger while i dont have air...so..its a big deal

even with all thats said..the weg still sounds like the best bet..am i wrong in that?

doc that motor on that c-aire what is it?..aside from the 4 caps on the old unit..you described my burnt motor

yeah resto its a castiron twin....i was VERY picky about what i was going to buy when i got it a few years back...i was hunting used...i wanted BIG 230v twin or better or 80gal or better VERTICAL,5-7.5 hp single phase, with 15cfm@90 or better..and it had to be a "known" name..i was shooting for comercial grade or as close as i could get on the budget..this popped up and i haggled my way down on it to around 250..and havnt seen anything neer it....anything within these specs used is 600+ ..in fact 2 offerings a craftsman(nope) for 1200 and a champion for 1900

so we have a shot of the unit itself those are cubical walls surrounding it so should give you "scale"(remember its 7 footish top to bottom) and that blasting cab is big enuf for mini bike frames, wheels, etc..a shot of its tag and a shot of the burnt motor pulled and in the shop
