    I have never worked with that particular drive, but I would be entering the motor parameters manually. Does it have an auto-tune function or just auto-detect? More complex drives would have an...

    Well now I agree with you. The motor nameplate does not match with the data sheet you provided - the data sheet was quite confusing. You did good on the motor.
  3. The rotor is compromised of rotor bars. The...

    The rotor is compromised of rotor bars. The rotor bars cut the magnetic lines developed by the stator current. This causes current to flow in the rotor bars which creates a rotor magnetic field. ...

    Thanks for all the responses.

    So I see that there are many solutions - I looked at several of the ones mentioned and will figure out which one suites me best. I am leery of the mechanical drains...
  5. Recommendation for Automatic Compressor Drain

    Can anyone recommend a good automatic compressor drain for my home shop 5 HP Quincy compressor?

    I don't know anything about them, and could use some guidance.

    I did find this one at MSC, but no...

    I had a set of Fowlers and really liked them. Bought 2 more a few years later - the new ones were Chinese and were crap. I sent them back and bought Mitutoyo. I still prefer my old Fowler to the...

    Not a chance on those! Very strong probability they are counterfeit.

    You are safe if sold and fulfilled by Amazon or by one of the real Mitutoyo dealers. When I bought mine I think I bought it...

    Looks a lot like my lathe. Mine is a 16 inch 6 foot and is a 1969 vintage.

    I do believe that those lathes came with 3 hp motors - at least mine did. I went back to a 3 phase motor to have the...

    Learn something new every day........

    I never knew this. I grew up in New Britain, CT - home to Emhart and Stanley and I never knew that Emhart owned Heli-Coil or that Stanley now owns them!

    I am a bit confused on why they rate the motor 30-60 hertz and only have a 1745 speed rating.

    The motor is only rated 3:1 constant torque speed range. That's not fantastic. Most motors bought...

    Please let us know how it works out.

    My 66 Bridgeport mill came with a Fairbanks Morse 1 hp motor. I replaced it with a Siemens aluminum frame 3 hp motor and dumped the multistep pulley - by...

    Where I come from we call it bulldozer troubleshooting (replace everything) instead of actually troubleshooting the problem and fixing or replacing only what was bad.........

    The tests I pointed...

    That is not a typical motor failure but it is possible.

    So it ran fine on a vfd for 7 years? No paramater changes in the drive?

    Could be potential bad connection somewhere.

    Really need to...

    Remember that when running a VFD you need to run it in sensorless vector mode(most drives today have this mode) not volts/hertz mode. Volts/hertz mode will have very low torque at lower speeds while...

    In my experience, not many of the drives I worked on gave you the ability to disable phase loss. But I'm getting dated now and not really keeping up with the latest bells and whistles of the new...

    Try L1 to L2. If that does not work then L1 to L3. Basically you need to hit the legs that power up the controls (and display). If the display comes on you are good.

    But not all drives can be...

    Don't think you specified what material the shaft is (or I missed it)- usually they are pretty exotic materials. Even run of the mill stainless steels normally don't hold up in a drum bleaching...

    As long as you can mount them, should be ok but they will not share load equally unless they are matched motors. The slip will be different between the motors which means that one will hog more load...

    Some people are real jerks on this site sometimes but there is a tremendous wealth of knowledge here.

    I would use AAI over KJ. But for what you are doing you are probably ok with KJ. AAI is not far from KJ.
