  • AC servo motors and long lay screws

    Went out of town to pickup some stuff I bought.(300 mile trip). The guy had a machine that has a couple of servo motors and controls as part of it. He was talking some serious money, so I didn't get real interested. Then he calls me and says he sold part of it, and will sell me any part for a hundred bucks. I told him I wanted those motors and screws. He backpeddled and said he would have to have 150 each for them.(I take them out). He was supposed to send me some pictures, but his camera is not working right.
    He called me with these spec's.
    screw is 62" long
    3" bearings on each end
    Motor with coupling is 9" long
    A/C servo motor
    Yaskawa electric
    type is Usarem-05cfj11
    3.6a
    w500 (wattage?)
    The screws are not regular ballscrews, but long lay screws. Maybe a turn or two in a foot.
    Probably going to be too fast unless they are geared down.
    What do you guys think? Will it work for a gantry router, hopefully to mill aluminum?

    Just got a picture, the lay length is about an inch, instead of a couple turns in a foot. Makes a lot of difference.

      David,

      Does the the package of screw and motor include the motor drive? AC servo drives can be very expensive, I have a couple of 1hp Emerson AC servo motors and drives that list for well over $4K for a single motor/drive combination.

        Supposed to have everything it take to make it run as part of the deal. Seller won't be there, just his kid, so I had better be able to figure it out or I am stuck.
        I have been acquiring some of these things
        but am not sure if they are what it will take. When I get tired of spending money (real soon!!) I am going to have to find some help to figure out what it takes to make it work. One problem I have is everybody's software says run thru the parallel port, but the stepper ones I have gotten only have serial ports on them. How do you run the software thru one of these serial ports?

        I got this one to replace one I sold after buying it on ebay.

            I made the trip yesterday and bought the motors and drives, ballscrews and the bearings and nuts that go with them. Hopefully I haven't bought doorstops! If i did, I have plenty for all the doors in my house and shop. Probably even a few extra doorstops to sell on ebay.
            Due to some parts already gone before I got there, I hope the 2 drives I got fit the motors I got, otherwise the money and the trip was a waste of time. Owner said all five drives were the same, so they just pulled 2 of them, which happened to be the two that ran the motors I was getting. Hopefully he was right.
            I was trying to get as much of the wiring intact as possible, when I ran into 2 transformers under the machine in a small cubby. Remembering Ibrewgypsie saying something transformers, I went ahead and bought those also. Boy are they heavy!One of them said 1.3KVA if that means anything to anyone. Some nice parts, hopefully will be of good use to me.

                  10 Years after: Have the drives remaines doorstops or do they actuate a mill now ?

                  Hello sandman !

                  Ten years after your post on this great CNC site, I stmbled over your post with the USAREM drives with the Yaskawa cacr-sr... drives..
                  Did they remained doorstops or did you get them working with a controller ? I would be highly interrested if you managed to do it !

                  Kind Regards,

                      Yaskawa servos and drives

                      Is he just a legend or does he really exists ?

                      Hoping that heĀ“ll answers (and revives the thread) ...

                      I have the same "antiquities" as home (and would like to see them running) !

                      Cheers, Rob

                        I was going to make the comment that those drives were old and obsolete
                        like 10 years ago, then I saw the date on the post.
                        So, Dude, those drives were obsolete 20 years ago!

                            But is there any way to reactivate them ?
                            I do not think they were obsolete 20 years ago, as mine were produced in 2003...

                              In the world of motor drives, one company (maybe the origionator) may market
                              a drive for a set number of years (maybe 5 or so), then declare it obsolete.
                              Then they come out with a new model, and sell off the old model to another
                              company. That company now markets this drive as "their" new model, when
                              in reality it is just the obsolete model bought out from another company.
                              This can happen 3 or more times, and the same old technology drive gets
                              passed off as new and current, only by a new owner. It is re-branding at
                              it's finest. That is why I say that your drive was obsolete 20 years ago.
