Need Help!- Servo motor magnets came off?

[CATCH22]

I dropped my servo motor on the floor today and it wouldnt turn anymore. So I took it apart and found that 2 of the 4 magnets inside the housing came off,is there a special glue or epoxy that I can use to glue them back onto the housing. It is a brushed dc servo motor off of a 1981 604 cnc excello mill, so they are really old.


Thanks Mike

I have used one of the super epoxy's, There was one made by Fel-Pro called liquid steel, but I don't think they are in business now or have been bought out.
But there are other super epoxy products out there.
Make sure you keep the same orientation of the magnet.

Thanks Al,

What about JB weld do you think that would work for me?

Thanks Mike

It sure looks a good product by some of the feedback and reports.

The last time a tried JB on magnets I found out it was magnetic.
It made a mess on the project I was working on as it migrated into places I did not want it to be.

I ended up using a 2 part epoxy and it seems to have worked.

Thanks for everyones replies!

PL Premium (sold in 10oz and 1/4 gal caulk size tubes) kicks the crap out of epoxy any day of the week.

The last time I used epoxy in a critical application it was to hold a heatsink to a high power LED array where it failed miserably (I used thermal paste surrounded by an epoxy perimeter). As the temperature rose, the epoxy progressively yielded until the heatsink had almost no contact and the array began to fail. Fortunately, epoxy stinks when it gets near burning temperatures, so I was able to catch the problem and turn off the power supply before the array completely burned-out. I used PL instead on the same array after cleaning off that epoxy crap and never had a heat problem again.

Not only has epoxy been getting more expensive, but it looks more and more like junk when compared to other adhesives which tend to be cheaper and more effective with longer shelf lives. Then you have the problem of the epoxy gelling-up and hardening in the bottle after a few months and a bottle full of stinky hardener with no epoxy to mix it with.
