Dave,
Recall we talked about early Slot its 21.5K thats really a 23K? I found some info from Slot it that should help identify the two.
From Slot It: About the new Slot.it V12/4 motor (MX16)
We've received several queries about the specs of the new 'small can' V12 motor (MX16), also known as V12/4. In particular, several customers have raised the question that this motor is specified as 23K RPM, whereas the previous one (MX06) was 21.5K.
Actually, the current V12/3 orange endbell motor (MX06) revs at about 23K too. A few years ago the factory changed the metal case of the orange endbell motor, from the old one with rounded off edges, to the actual one with squared edges. This unintendedly and unexpectedly increased the RPM from 21.5K to 23K, but the motor specification was never officially upgraded.
The only difference of interest for our customers is the endbell, which is now a single piece in order to keep the brushes more firmly and hopefully have a more stable production across batches
As far as performance is concerned, the new 23K V12/4 MX16 motor is expected to be the same as the old 21.5K V12/3 unit.
Please note that indeed the new motor shall be called V12/4
