Hoping I'm in the right forum here. I guess this applies to alot of motors.
I have a couple Delta R.I. motors apart and the necklace springs on the way (and believe me, that was hard to find). Bearings from Accurate tomorrow.
The problem with the motors was that they would not start with force on the shafts. Upon further inspection, the spring to the necklace assemblies were stretched. As well, the motor shop guy that looked at these threw in the towel and showed me the wire on one of the armatures that came loose. I have re-soldered the wire, re-insulated the winding and was looking into cleaning the stator and armature. This prick gave me one motor back in pieces and I still have to go back to see if he still has a cover plate and bearing. I'm livid I'm on my own.
The black rotor has also been turned to the point that it may not have another left so this will probably be it's last repair.
Here lies the confusion. I have asked motor shops and people that have worked on motors what is up with cleaning these. No one gives a straight answer or complete if any in regards to the armature and stator.
Are these coated with something?
How do you clean these if they have rust or over-spray from insulating?
Can you spray insulating varnish on them if these were previously cleaned wrong?
I think I read somewhere about not using anything electrical or metal or abrasive or something and stay out of the laminations but I don't really understand this so I was hoping the big mystery could be unraveled.
If these were previously cleaned wrong, can you just solvent wipe and insulate with red varnish to fix?
I also had (still have) Chinese bench grinder that I cleaned the rust off and now it smokes so I'm sure I did something wrong. My thought is that many motors could be saved if this subject was clarified.
I have searched for this and have found nothing.
I'm hoping to get the answers here and save me and future lookers from ruining their motors. Thankyou.
I know we all like pictures so here you go:
