Air Compressor motor help needed. Anyone speaks "electrical" ?

[angelo c]

I have a blown electrical motor that used to power my shop air compressor. It was a 3hp, single phase,1725 rpm 215 frame motor. I am told a 215 frame is not common to find. I just want to remotor the compressor but some motors are in the $700 range. I am better off buying a new compressor altogether ? I reached out to an Ebay seller and they said a L1510T frame/motor is what I need. also a 7.5 hp....all I want is air ?
what does all this translate into and can an adaptor be purchased or made to use a L1430t motor run on a 215 frame ? Jesus this is confusing.

You say burnt up... blew the windings?

Take it to a place that rebuilds motors. They can rewind it and put you back in business.
I’ve got a few shops that do it around here.

It's pretty easy to mount just about any motor with a base mount to an air compressor, sometimes you have to drill new holes. You could even use a 3600 RPM motor if you could get a pulley that is 1/2 the diameter of the current one and you'll probably need a shorter belt.

Harbor Freight has a cheap 3hp, 3600 motor.

+1 on the rebuild. I bet you’ll end up with a better motor after the rebuild, for a similar priced horror freight motor. What are the “blowen up” conditions? No start, noisy grinding, noisy humming with no run, low power?
It usually is one of four options.
1 bearings are shot
2 windings have shorted.
3 the brushes have worn away
4 the air compressor unloader valve won’t release the pressure in the cylinder, and the motor can’t over come the pressure (think hydro locking)

Go to Lowes, or somewhere similar. You will be dead before this wears out, unless you use it in a business.

kept throwing breaker.
no noise
motor is apart and in scrap pile now.
no pressure in tank, valve was released. compressor motor turns freely.
thx

Find a different motor, may have different wiring, different shaft, capacitor, etc. Make a dozen online posts, look for a pulley that fits, etc, and so on.
Or just sell the old compressor carcass on facebook/craiglist for $50-$75, and go buy a new one for $400 or so more, and it will be done and settled tomorrow.

Just saying, life is too short.

Go to TSC, or wherever.

 

[Fish]

Just buy a new one for $500ish, intead of investing a few hundred and a month or two.

You may learn a lot, or you could be focusing on life.

Unless you desire to be the online "compressor" guru!!

Which pays very little......

John, you seem cranky today....hope all is well.
basically I was looking to ejdumacate muhself some on compressor motors. wtf did the "frame" numbers mean ? and why a 3hp motor is now a 5hp and might even need to be a 7.5hp.... I got the RPM/pulley/shaft thing figured out ok.
