Today I wanted to share something new that came across our bench. One of our customers brought in a DC motor from a very old CNC machine. Many times keeping these machines running is critical in keeping the business doors open.
As you know finding parts for these old machines can be nearly impossible, or if you do find what you are looking for the prices are so astronomical, that they leave one searching for alternatives.
Needless to say, I was very happy to be able to help this customer with this task and have a small part to play in keep this old “STUFF” running.

0:11 – This is a a DC motor off of a CNC machine, it’s one of our customers, and has absolutely no identification on it whatsoever
0:23 – This thing has got a gear, and it runs the table for the CNC, after we repaired it we went ahead and tested on 12 volts and it’s kind of interesting, because on this end you can see by the photo there’s another armature on this end, which indicates it’s putting out current
0:40 – Because it has no connection between these two unless the armature is turning, without any information on this motor we really didn’t know what we had, so I took it all apart and I repaired it
0:52 – The bearings were bad and I put it together not knowing what this thing, all the functions, so my own meter test, which is audible, does this, and then nothing here, and so my thought was there’s something wrong with that upper armature
1:11 – Well once I got it together and did my testing, it was interesting, I’ve got my meter set back to DC voltage, and we’re just using the 12vt battery because I don’t know the voltage of this, but interesting what I found out
1:29 – Here’s the motor turning at a slow RPM, I would guess maybe 300 not sure, DC motor but this is interesting, this end is producing 9 volts, so my thought would be this is a reference for the computer to know what this thing is doing
1:54 – In order to control it we had no continuity with the ohm meter, but yet when it’s running we have current
1:58 – They’re so interesting the way they built this
