I recently acquired a Craftsman 3HP 15gal 150psi air compressor with a burned up motor. Anybody have any clue as to where a new motor can be obtained? I googled air compressor motors and the first site I went to stated that the motors they provided were good for all compressors, but craftsman. What gives?

Thoggard,

You can find a motor on ebay. Typically what you will be looking for is the rpm and voltage (120 volt or 240 volt single phase) of the motor. This can be found on the name plate. The mounting and type of motor is also on the name plate. Your motor is probably a 56C flange but this is not necessarily fact.

You do want to get a compressor duty motor. Now one thing that you might want to know is that a bad pressure switch may make it look like the motor is blown.

I wish you good luck with your compressor. I bought a 3 hp motor on ebay for $50 so they are cheap.

If you have any questions, please ask.

Cheers,

Ben

Older compressors required a motor that could hard start against the pressure. Before purchasing another motor, carefully check the nameplate on the present motor, and if you are not sure that a standard NEMA motor is adequate, counsel with a good electric motor shop in your area.

thoggard, What is the vintage of this compressor? 10 yrs old or 100 yrs old? May help in determining appropriate advice. Oiled? single cylinder? twin cylinder? screw-type? Thanks.

Tractor Supply Company is a good place to shop for electric motors.

Thanks for the information gentlemen. I will certainly try the bypass before going shopping.

pitchnsplinters,

As far as the age goes, “2001” is imprinted on the bottom of the nameplate so I am assuming that is the year model. The label upon the motor housing states that it is a single cylinder – oil free.
