What is this motor tag telling me?

In the States we have three wires. 2 lines and a ground. Line to Line is 220-240, Line to ground is 110-120.

I would assume that the higher voltage is for star connections and the lower is for delta connections. If the delta connections are used, then a cheaper VFD could be used with it.

by cheaper vfd you mean 3x230v? (or is it 3x110v over there?)

Old Mart : It is. It is now installed, wired, and tested. It is alive. Now I have to get some belts. 4 of them. I did fix the pulley and it is balanced too. I still need to clean out its new home in the shop. I am thinking about were I'll need access once it is on the concrete. I don't want to ever move it again.

I'll get some photos soon.

Keith Rucker (youtube) has a K&T now. His is a swing table.

In the last 3 months it has been really crazy. I ended up building a motor for my kid's Mini Cooper (lot of shop time) and I picked up a Case 580C to do some yard work. Both are now running but it now getting dark out in the country after 4:30 so I am getting some shop time back.

That motor is 10 hp, it must be a big K & T mill you have.

That is a Y connected motor at both high and low voltages. It is a 9 lead motor so there is an internal Y connection of 3 coils and the remaining 6 leads are the ends of 3 coils so you can connect in series with internal Y or parallel a second Y with the first.

What it means is they were too CHEAP to print two wiring labels. So they made just one for two kinds of motors.

Hopefully the buyers benefited from their frugality, but I wouldn't bet on it.

I would bet that wiring label was used on more than just two motor models.

Hi Guys,

Quite simply it is a dual voltage motor, it can be used on either voltage by altering the links on the connecting block. But not both voltages at the same time.
As Old Mart said ideal candidate for a VFD.

That second picture show the required connections on the terminal block for the two voltages.

I would assume that the higher voltage is for star connections and the lower is for delta connections. If the delta connections are used, then a cheaper VFD could be used with it.

Thanks. I stopped last night at putting this motor into my K&T. After second guessing myself 20 to 30 times I decided to ask here.

Again thank you for helping.

Single voltage means the leads aren’t brought out to selectively wire for dual voltage.

Might be HI or LO but not both. Plate says dual, so ignore that part of sticker.

3 phase. My Baldor 7.5 h.p. 3 phase has that same note on the inside of the electrical connection cover. Ignore the stated, "Use a manual momentary start switch only". You can go to the Baldor website and download a pdf file with everything you could want to know about that particular motor.

3 phase
low is 230v
high is 460v

[outlawspeeder]

The tag on the motor has low voltage, high voltage, single voltages???? The the ID tag say 3 phase. It's not both 3 phase and single? I've never heard of such a thing?
Thoughts? Is the 2nd pic just a sticker they use on all motors?
