good morning ,so I'm working on a old grain elevator and i need to find out some motor taps on an existing motor
the only thing i can make out on the nameplate is
I'm pretty sure that the last 3 are counter clockwise

Hi there rhiphi,
That is a shocker of a code.
A google search came up with this thread, blast! crazy

What is it that you need to know with respect to this motor?

If possible, a picture of the open terminal box would really help and maybe the nameplate.

There is a lot of people here that are very experienced in motors, we just need a bit more info.

Check if it's 180VDC or 3-phase AC.

You might poke around this website:

Let's parse the number:


fxb = Cooper power system recloser control for DC Motors (?)

143TC = NEMA size 143T;

C = C-face mount, motor bolts up radially around the shaft.

F = class F insulation, a severe duty rating.

ccw = counter clockwise; normally used to indicate that this 180VDC or 3-phase motor MUST be wired for such due to the nature of the driven load.

I swiped this from the Furnas site but the last page has a lot of different types of motor designs and the wiring that will make them work from a drum switch. It has helped me sort out some strange stuff I have run into.

If its got 9 leads, its a 3 phase ac motor, dual voltage.

I have never seen an ac motor marked for direction, except single phase.
So what do you have? 3 Phase or single phase? And what voltage? You have not provided enough information.

Sorry guys took me some time to get back to The site
what i have is this the guy bought a used grain silo
the motors are in a heap and some boxes
this motor is for lifting the grain into the top so i can hit it w/ 120 or 240
but there is not much left of the name plate to say the least
1750 rpm 60 hz
115/230v 15.6 7.8 amps

no nameplate that i can see
but i guess tesla found what i'm looking for
