old GE single phase motor wiring diagram 1

[Tmoose]

I got an old motor missing the cover with the wiring diagram.
Barely readable nameplate may say 5KC184AG201BU
Googling that model number suggests its a GE, and the AG in the model number is probably wrong.
Anyhow, wired as-received It starts and runs solo on 110 OK, drawing ~ 10 amps, which is about half the 19.5/9.5 FLA on the nameplate (for 110 v operation).
There are 11 leads coming from the winding crudely friction taped together like this
9-6-8
5-7-10
3-12(!!)
2-4-white
11-black

I'd like to wire it for 220 and give it a try running an old Curtis air compressor.

Does anyone know where to get a wiring diagram?

thanks

Hi Tmoose
I have a motor wiring diag which is possibly what you are looking for, but having difficulty posting it on the message page. I've scanned it & saved it as a .jpeg file.

I have followed the instructions regarding uploading the file to ENGINEERING.com but no success.
Any ideas?

it is a little tricky sometimes.

You have to know where the jpg is saved. I normally save right to the "desktop" cause its easier to find than digging down thru folders off "my documents" etc, etc. The scanning software may default to saving it almost anywhere.

Off to the right of "Step 3 attachment" is a link that saye "or upload your file to ENGINEERING.com" . Then "choose file" and you have to navigate to where the scanned jpg is. Note a "desktop" icon is off to the left, so you can go there directly, if that is where the file is stored. slide the scroll bar over until you can see the file you want and click on it to select it, then click on "open". The previous screen should open, with your selected file name to the right of "select file" button on the left. Click on the "upload file" button on the right, and a new window shoulg give you a blue link to upload file to your post, or something like that. then fill in the wstep 1 message window, and finally click on submit post.

Hope this works

The picture file came through fine.

The 11 wires suggests its a 3 phase motor, based on a variety of dual voltage wiring info on the 'Net.

However The link below mentions a 1.5 HP motor running on 110/220 (certainly single phase). The first first 6 characters in the model number (5KC184) are the same as mine. The I'll look harder at the mutilated name plate to see if phase info is still there.

When I ran the motor solo on 110 and it drew ~ 1/2 nameplate that seemed "normal" to me. Of course with no load it was not much of a test. Seems I've been around larger 3ph motors that ran single phase when a fuse blew, sometimes with no obvious symptoms, sometimes humming real loud

It's starting to look like a 5 HP snowblower engine "from stock" may be a more practical means of powering this compressor, as often as I'll be using it.

The 11 wires suggests its a 3 phase motor, based on a variety of dual voltage wiring info on the 'Net.

Only if two of the leads come from a protection device. The power leads are in multiples of three.
3 leads
6 leads (common in IEC land)
9 leads. (common in NEMA land)
10 leads (Generators only, never motors)
12 leads (rare, often special purpose motors)

FLA= Full load amps (running) 9.5amps vs 10amps is about right

the 19.5 is the starting surge and normally about double the running amps.

by the way, single phasing a 3ph motor makes it over heat and reduces the hp/torque rating not a good practice.

believe you have a single phase motor so that sould not be a concern

Are there a capacitors fitted to it?
If so, then it is signal phase.
It could also be 2 speed which would account for other wires.
Additionally, dual voltage motors have separate windings & connections are brought out to enable series (220V) or parallel
connection (110V) operation.
Also there is usually a starting winding (another 2 wires).
You may have to open it up; & identify individual windings by measuring their resistance.
Does it have an internal starting switch or relay?
Drawings I have are 1940 vintage!
