Has any one replaced bearings in them? I know that on some of the older servo motors you have to install a keeper in the motor to keep the magnets from degrading.
I assume that all the recent ones have rare earth magnets in them and I don't think they will degrade?
I would really like to get the machine up and running Monday to buy some lead time on getting a new one.The electrican on hand wasn't much help and started in about losing the parameters for the resolver if I took it apart.Seems to me if the battery is good that wouldn't be a problem. I don't under stand the mentality of people sometimes, the motor is junk as it stands,the only thing I will do make it junkier? or fix it until to run until we get a new one. It was running when I took it off so electrically it is ok. The operator told me the gear box was bad because it had lost all its oil and was making bad noises.
After a bad day and late in the afternoon I fell for that without checking the motor after I pulled it to get the gearbox off. The coupling was shot so I replaced it and sealed and oiled it then found the noise was the motor.The front bearing is shot.
The equiptment manufacturer wants 40K for a new motor and gear box.The gear box is no longer made. BS!
So if any body can help I would appreciate it.I am posting in general because there are quite a few maintenance machinist here.
