Anyone know what the name of the song is ?

By leaving a space on edge of riser from band,,,lots of cooling....We have been doing the same for years .never been a problem.
-
By converting a banded GE CDS com to a solid riser v-ring com, you realize you effected the cooling capability of the armature? There's a reason for those open risers.
Nice repair never the less.

I have 2 questions. The commutator part where there is a steel ring to release the commutator copper, what kind of tool do you use to remove that ring. Also, if that ring is glued by epoxy(i think), how do take off that glue first before you take the ring off.
-
I bet that repair wasn't cheap to do. You've done a great job on it....
-
I know this is the workmanship of a great team not just one. good work guys.

Was this motor for a lift?

The DC motor operates on a Paper Machine.

That's an impressing motor! Wow. I like how it slowly runs up to speed. What technical data may it have (power rating etc.)? First it looked like an AC machine to me... but I'm not an expert.

Thank you for your interest in this Video. The Technical data of this motor:
200hp at 1150rpm, 500VDC. If your looking for the KW rating the output KW rating is 149200 Watts. Hope that helped

Yes, thank you. Would also like to know if you soft started it slowly or not, and whether the end rpm in the video was full power or less than full power.
SlyFox20061985 3 years ago
With this DC machine there is two different power sources required. In order to "Soft" start, full voltage goes towards the shunt fields (ranges from 210VDC to 230VDC). Voltage is slowly rased in the Armature winding to get the "Soft" start effect. All DC machines in our shop are tested to there full capacity. Hope this helped. And once again thank you for taking an interest in my video.

Also one other thing, when we test the DC machines we run them for a minimum of two hours at full voltage.
