Looking for updated part number for escap motor

Electromechanical Motors, Actuators, Solenoids and Drivers

In our lab we have a Nonius Single Crystal Diffractometer containing escap motors. Recently an encoder/motor part for the Kappa CCD gears on the instrument corroded and we are looking to replace the part.
I couldn’t find the specific part number in the catalogue on the website, but have found some similar parts so I thought perhaps the part number is out of date. The instrument is also quite old so I don’t know a lot about the specific electronic requirements of this motor, so a data sheet for this part would also be very useful.

The part number for the escap part is: 26L 28 216 24
It has a 2mm pin and 26mm casing diameter.
If there’s other information that I can provide that you think would be useful in determining the appropriate replacement please let me know and I can try find it.
I’ve also attached a photo.

Thanks,
Sam

Hello,

I could not come up with anything similar to this one.

Might try giving the folks at Portescap a call. Almost certainly a part number they’ve discontinued or did as a custom a while back. I’m having no luck finding documentation on your specific part or a decoder ring for the numbering system, though the “26” would appear to be a diameter. and what we’ve got in matching listings for that would be here.

If you get no luck there and that motor’s in good enough health to use as a reference point, a person could put some pixies to it and measure how fast it spins to get another data point.

Also, it might not be a silly idea to take measurements of the pinion gear and see if the folks over at sdp-si would have something that’d work as a replacement. One might open up new motor options that way and if the assembly is still serviceable it’s probably prudent not to try getting the pinion off it.

Thanks for your comment, this was really helpful! I already spoke to Portescap and they sent me to DigiKey, but have also reached out again to them to see if they at least have a data sheet for it. I think one of the parts on the listing looks like it could be a viable replacement. I was thinking that the 24 may be 24V, but that’s very much just a guess. Have also now started looking into possible replacement pinion as well which might also be necessary, our in house mechanics shop seem confident they could get it off to add it to a new motor but could be an issue that comes up for sure. Thanks again!
