Their nominaly rated at 18V. They will run fine on 12-22VDC, albeit slowly on 12. All the aristocraft motors are the same I believe.
Aristocraft B Unit Bo-Bo Kitbash.
Good Morning all,
I bought a "B Unit" from "Evilbay" and wish to Bash it into
a Western Australian Diesel Unit, When it arrived home I tried the Motors and they seemed slow to me in running, A Mate suggested they maybe 20Volt!, so I thought I`d ask you chaps,
It is around 1990 Circa` and I have no Idea.
Which then begs my next question?, Is there anyone out there
with two 12 Volt Bogies {Two Axle} who would be interested in
Swapping the 20Volt for 12Volt Units?
John.

The USAT units tend to run faster, maybe that would be a better base to start from.

The c. 1990 FB-1 units work quite well with 14.4 volts, (12 NiCad cells) and move at a decent clip. My dad and I converted an A-B-B-A string around that time for a friend in exchange for doing the video for my sister's wedding. They ran convincingly quickly enough. I don't think you'll have anything to worry about.
If you use Aristo's LiIon packs, I believe they're 18 volts so you'll get even more speed out of them.

You may want to have a look at George Schreyer’s article on tuning up the early motor bricks that were used in the FB-1.

We are getting a little off track here. John: very little, if any, large scale runs at 12 volts as a nominal max voltage.
Maybe we should ask you now why have you selected 12 volts?
Virtually every large scale power supply is a minimum of 18 volts.

Good Morning All,
Really there is no reasonable reason what so ever to use 12 volts
over 18 volts, other then the fact of Habit, I`ve always done
so as well as I`ve run all my Battery Powered R/C Locomotives
on 12 volts too, so I guess I`ve just never stepped out of my
comfort zone before.
I really don`t wish to build a Diesel Engine that runs like a
"Racing Tadpole" all over the place, I`m getting toooooo old
to catch the bloody thing ;-}}, I much prefer a sedate and
more Prototype speed in my Models.
It would seem all I really need is to leave the Original Motors
fitted and run them on the 12 volt system for a sedate speed.
Thank you all for your collective input, That is what makes
these Forums a Bottomless Well of Information to all.
Best Regards,
John.
