ECN Forum Forums General Topics of the Trade General Discussion Area motor taps

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
fxb143tcfr7033bawccw
I'm pretty sure that the last 3 are counter clockwise
can somebody point me in the right direction

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

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.

Good morn Trumpy,
What I'm looking for is where to put my voltage.......
ie........1,4,9
3,6
7,8,2
for 120 volt
The jbox is in bad shape
there are some leads tied together
Didn't write down the the grouped numbers
I'll drive out there to see if i can read any more info

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


You might poke around this website:

Let's parse the number:

fxb143tcfr7033bawccw

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

http://www.cooperpowereas.com/Products/RecloserControls/FXA-FXB.cfm

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
thankx
