    TRANE CHHC1C2 Motor Rotor

    From the attached picture, is it considered as a defect rotor?

    Rotor Bar Test results No current fluctuates at 55VAC 80Amps.
    The motor winding was burnt out.

    What is the TRANE Motor Rotor part# for CHHC1C2F0L0 Screw compressor?

    Where I can buy the replacement motor rotor for TRANE CHHC1C2F0LO Screw compressor from? What part# is it?

    Hard to determine from the picture but the rotor laminations do not appear to have seperated. I think you will have a hard time purchasing the rotor as an aftermarket part.

    Depending on the burnout severity it is highly likely contamination will have been carried through the compressor rotors, which when combined with the acidity produced as a by-product of the burn will compromise the rotor bearings and compressor.

    If your customer wants a gurantee of reliability after the reapair an exchange compressor, system clean-up and diagnosis/rectification of the cause of the motor burnout is the best option. Rewind the motor and you take a big gamble on reliability

    You're not going to be able to get that part. If the motor is burnt, get a new motor. By the test, it doesn't sound like it's too awful bad. What are you going to do rewind the stator? Like to here more about this one.

    that is not a broken or cracked rotor bar. purchase a new compressor and move on. i applaud the interest in finding a root cause but even your own testing found no cracked rotor bars. the compressor is a replaceable item (is that a shame or what). the tolerances are too tight for any real field repair.

    Where in FL are you? I know a shop in Clearwater that does rewinds on Trane screws, CHHN, CHHB and CHHP's with good results, so they could probably handle one from an RTHD. I was a little sceptical myself until I found out they do all of them for Pinellas, Hillsborough, and Pasco schools. As long as there's not a rotor (screw) issue, they'll do it for about a third the price of a Service First replacement comp.

    You may want to think this one through

    I would have to agree with jayguy on this one. Not taking anything away from ChillrWisperer, but if you can get parts the stator and rotor would have to be a matched set from the motor provider. Most likely that going to be A.O. Smith as they have been making motors for the Pueblo Trane factory since it began. You have too many variables on a bad burnouts that can really come back later and bite you in the a$$ (note dollar signs). The last Trane CTV motor burnout I did we went another way (due to customer request) and it was a miserable time afterward.-GEO

    You're not really saving anything if you have to do it twice.

    Get the right OEM parts for the job and sleep easy at night, or you can do it on the cheap and wait for the inevitable call when thing crashes.
