If it's the Loctite glue I'm thinking of, heat is going to be your only "unglue" solution.

As far as a new or used servo motor, I would probably start with Ebay, especially being a yellow cap. A quick search for Fanuc DC motors brought back 42 items. There are also some Ebay stores that have some of the older control stuff. There is also a company based out of Tennessee, that has older Fanuc products. They do a core charge if they have it in stock(they send you one, you send the bad one back, and they recondition it and knock off some of the price). I have a contact number for them at work, and can post that for you tomorrow.

And then there's always Fanuc. They may have one, but it will come with that nasty Fanuc price tag.

Thanks codyst, I have found 2 on ebay that are very close. Im sending them some info on my motor to see if they can identify it. My motor's plate is blank except for 4 things.

(2000M) RPM?

84.11 Date?


B-481694 Serial #?

011 I have no clue.....

The glue is a 2 part epoxy type of glue and Im not sure how to break the magnets free yet. i had heard that heat was bad for magnets and was thinking of freezing the housing before trying to press the magnets off the wall with my Arbor press.

I dont think i can afford a new motor from Fanuc.

You're correct, heat typically isn't very friendly with magnets. You might be able to freeze it and get them off, but I'm not sure. I've done it to bearings with great success, but I've never tried it with something that is epoxied on.

The company that I mentioned is Tie. Their phone # is 615-471-5070. Website is http://www.fanucworld.com A few of my customers use them quite often and I've yet to hear a complaint about them. From what I gather, they sell it for new price, or whatever the going price is for a "vintage" Fanuc part, and when you send the old one back you get somewhere around 25% back as a core. Don't hold me to the percentage; the customer I was with today couldn't remember the exact amount he got back.

Thanks for the number codyst. Im in the process of communicating with them to try and figure exactly which motor i have.

I have left the motor housing/magnet soaking in carb cleaner over nite in hopes of softening the glue some. I have got some info to determine which way the magnets are installed and now am pretty sure i only need to loosen up one magnet. i figure since the motor worked with 3 loose magnets with the proper orientation that i can recreate that with the magnet(s) loose before gluing them back in this time. I appareiate all your and Petros help with this and will let you know waht it takes for me to get the machine running again.

The carb cleaner had little to no effect on the magnet glue. I got a hold of the company that I got the Loctite glue from and they contacted Loctite for me. Loctite recomends heat, around 350 degrees or so. and they sell a glue softener. I ordered a pint of the softener. Its coming out of Chicago and should be here by Friday or so.

I also contacted the extremely nice people at fanucworld. I emailed back and forth with a lady named Peggie. Peggie was very nice and informative also. Fanucworld gets between $2800.00 and $3200.00 for a rebuilt and new fanuc servo motorslike mine. That price would just about blow my budget considering I got the whole machine for around $6500.00.

I also contacted a couple of people with used motors for sale on Ebay. Im not sure exactly which way im headed at this point but will keep you informed of my sucess's/ failures.

I have another contact here in Indianapolis that rebuilds servo motors. I'm not sure what it would cost for shipping and rebuilding, but I could give him a call if you like. It'd probably be Thursday morning before I could get in touch with him. I'm in Warsaw, IN until Wednesday but could get his number when I get back to the office.

Any other contacts would be appreciated codyst. Thurs will be fine. Thanks!!

I'm re-installing 6 Star swiss type lathes, and 1 new Star swiss type, and was asked to extend my stay an extra day; so I won't be back until Friday. I'll try to see if someone can get his number out of my folder at the office and send it to me.
