Hey all, pictured below is a rotation motor I pulled from a first-gen CPA2 (serial number < ~10300). As you can see, the part number on it is SWF 403.278. I'm trying to collect some information on the different motors found in various Jobo machines, in the hopes of collating and sharing the in some form, so that we have a verified record of what motors are used where and when. The information provided first-hand by Jobo is fairly incomplete, referring (here:https://www.catlabs.info/how-to-choose-the-right-jobo-processor) only to a first gen motor that had a single bearing (the one pictured above), a second generation motor that had two bearings, and then later motors that were "strengthened" to support the weight of larger tanks like the expert drums. Here's what I've put together so far regarding the motors and circuitry I've come across:

SWF 403.278 - CPA2/CPP2 first gen rotation motor (24v)
SWF 402.878 - CPA2/CPP2 second gen rotation motor (24v)
SWF 403.304 - CPA2/CPP2 final upgrade motor (supposedly, have not confirmed this myself)
SWF 403.279 - ATL-1 Lift motor (24v)
Bosch 0 390 206 692 - ATL-1000/1500 rotation and lift motor (12v)

All of the rotation motors in the CPP2/CPA2 machines I've encountered are 24v. This indicates to me that the later rotation motors draw more amps than the earlier ones, which probably necessitates a beefier power supply if you want to upgrade. I've examined a few of the transformers, and they appear to provide 20v/1.2A on the machines I've examined (1.15A on the CPA2), which is sort of interesting given that the schematics seem to indicate that this should be a 24v supply. I'm guessing this is because the speed is controlled via voltage (7-23v according to the schematic), and the motor's top speed is never actually used, meaning they discovered they could save some money and put a smaller transformer in there.

If anyone would be interested in participating in collating this data, please take a peak inside any Jobo machines you might have on hand and reply here with the make of the machine, the serial number (or serial range if you're uncomfortable sharing the exact number) and any model information you can find on the motor. I'm particularly interested in late-model CPP2, CPP3 and ATLs from 2 onward. If you can find the power output of the transformer in the machine, that would be helpful as well. I'll create some sort of document from all of this and share it here.

The CPA2/CPP2 are 2nd generation processors.
Thus their motor hardly can be 1st generation, unless same motor was still used.

Good to know, though that does introduce some confusion, since I do have in my possession a CPA2 with a serial number under 10312, which indicates that it is a first-generation CPA2, and in fact has a different motor from the the other machines I have on hand, all of which have serial numbers from the second batch and all share the same motor (that is different from the machine in the first batch). So while the document seems to refer to all CPA/CPP devices, it would appear that they actually refer to the CPA2/CPP2? I'm referring here to bulletin #B019, which does refer to the CPA2/CPP2 in the title, but then goes on to refer to CPA/CPP machine.

Then we got a misunderstanding: You meant "first generation of CPA2/CPP2. I understood "first generation processor".

And Jobo USA by ignorance added to the confusion.

Sorry for resurrecting an old thread, but where does the 402 876 motor fit in? Or was the above number a misprint.

I read long ago that some of these motors are stock automotive parts. 24v wiper motors to be more specific. And before you ask a lot of big trucks use 24 volt electrical systems.

As are the circulation pumps on the ATL Jobo Series. Volkswagon water pumps to be more specific!

Seems like there are a number of (publicly) undocumented production variants. I have an early CPA2 (Sn. 10198) with a rotation motor marked 402 446.
