Hey Duke,
I 100% agree with you on swapping the old motor for a new 3ph asynchronous motor instead of paying almost $1000 to only a new drive. I do not recall exactly what i paid for the 3200i,...

Hey Duke,
I 100% agree with you on swapping the old motor for a new 3ph asynchronous motor instead of paying almost $1000 to only a new drive. I do not recall exactly what i paid for the 3200i,...
One more note, have a look through the documentation of the drive to find the scale of min/max output voltage of the drive. Because if you are going to have the ability to rigid tap, the minimum...
I think https://inverterdrive.com/ ships to the US.
I got the exact same motor you have attached a picture of. I am running the sprint 3200i unit at 240VAC input. The 3200i drive does have tacho...
Hi,
This is a PM DC motor.
Sprint Electric have reasonably priced drives for this motor.

There is also RC-supressors that can be connected in paralell with the relay coil if you experience any problems.
Nice looking machine! what are you going to retro fit it with? Also, do you have any of the limit switches for sale?
I think Kern and Struder uses some type of synthetic granite in their machines.
Yes, shorting to the metal housing, I just wanted people to know that connectors made with metal housing do at some occations make really hot sparks as well. But sure, if it is on your own hobby...
I am a industrial electrician by trade and reading people writing that metal connectors do not cause fire makes me wounder where they get this claim from. I have seen die moulded aluminium connectors...
This looks like a Harting connector, https://www.elfadistrelec.no/Web/Downloads/71/26/04347126.pdf
As the title says, limitswitches for a DM4400. The circular NC type.
Do you have any of the limit switches for sale?
Thanks

Hello,
A few years back I acquired a DM4400 for an good price. However, it turned out to have bad spindle bearings and I had to do a spindle rebuild.
You can check out how I did that in this...
You might want to look up the duty cycle on that ESC, because of rc components are usually never ment to be run at full load over time. U probably want some good airflow going over that thing as...

Is there air running over the drive board? Allot of dust? All fans working? Filters are clean? Spindle moves freely when you turn it by hand?

Hello
What type pull stud does the 4400 use ?
BT30 45,°60°,90° or iso30 type ?
I did look in the dm4400 manual but it only says pullstuds are supplied by Dyna.
You are correct Marty, the sleeve has a groove in the middle and this makes the sleeve expand when you apply hydraulic pressure to it.
Sorry for not keeping you guys updated.
I received the bearings a few weeks after my last post. They where successfully installed, and the whole operation went better then expected to be honest....
Good to hear Keith
Been a while since this was updated, what is the current status ?
Got them from a dealer in Norway. Dyna Mechtronics wanted 210$ for them now, and I have to add 25% in import taxes to Norway. I would probably save some money by purchasing them from DM, but I feel...

Take a look over at Denforddata.com they might be able to answer your question better. Maybe this helps -> Link
Dan, I cant thank you enough for taking the time to disassemble the spindle on one of your machines. You saved me allot of head scratching!
A couple of days after your last post I did exactly what...
