If it's the same model motor, you might be able to rewire it for your 230V
supply. Look at the nameplate or inside the wiring chamber to see if there is a
wiring diagram that details wiring connections for different voltages.
Barring that, you might search the Mfr's website (if they are still in business)
or Google for the make and model of your motor and see if there is any data on
it that details the wiring instructions.

What's broken on the original motor? There isn't a whole lot to go wrong
with these, I've yet to run into one I couldn't fix.

Me too. Usually it's just been corrosion that can be cleaned off and/or
lack or lubrication.

I tried first by replacing the capacitor. I could not pry off the
pump because it was rusted shut and bolted on well.
The repair guy said it was a break in the winding. He is rewinding it
for $170.
I was thinking of doing it myself but I was told that rewinding it
manually is tough.

BTW, I cannot refind the "for sale" motor on the web anymore.

BUY IT! You'll thank yourself 10 years from now! The speed diffrence
wil be neglegable, the duty-cycle will be such that the motor will
enjoy a much longer life... if anything you could step-up RPM by
adding pulleys and a drive-belt rather than direct-drive coupled as it
is now... The pulley/belts would also minimize start-shock to the pump
by softening the inital roll in of the motor...

Or... of 208V. If you have a "three phase" circuit
coming into a building, and you run two "hot" wires
to your appliance (or motor), the effective voltage
you're getting is 208V.

There's enough overlap so that a standard 240V appliance
such as, say, a larger air conditioner, will work more
or less ok on 208V. And vice versa.

But there is most assuredely a difference in the
two circuits, so for optimal results, you'll want
an appliance (or motor) designed for the specific
wiring in your facility.

Depending on the age of the motor it could be rated 230V which now has crept
up to 240V just as once we had 110V, then 115V then 120V as nominal

http://en.wikipedia.org/wiki/Mains_power_systems

There are two different flavors of 220/230/240 volts. Some places have a
simple system with one wire hot and one wire grounded. Other places have
a split system where the voltage is split in half to get 110/115/120 volts
relative to ground, by adding a additional "middle" conductor that is the
grounded one.

In theory, it's 230 on a single phase - neutral circuit here in the UK now,
but in practice, it's actually nearer the previously accepted 240v for the
most part ...

Most countries are 230 Volts (50 Hz) with some exceptions, such as North
America, parts of South America, Japan, and a few others. Nearly all of Europe
is standardized on 230 Volts 50 Hz, although outlet/plug shapes still vary from
country to country.

Europe.

I also noticed just last week that Malaysia and Singapore use 230V (@50Hz).

Continental Europe used to have 220 volts (before that it was 127 volts in
some places), the UK used to have 240 volts. Nowadays, the common voltage
is 230 volts -10% +6%.

And where you have 277 you almost certainly have 480. But I suppose it is
possible to have 277 alone (is better to use than 120 for lots of fluorescent
lighting) or maybe even a 554/277 Edison style single phase split system,
where three phase distribution is not available and the higher voltage is
desirable for large areas of commercial lighting.

yeah, where do you find 280 volts? it's either 208 or 230.

If you are in North America, and have 120 VAC to the outlets, what you
call 220 or 230 VAC in your home is actually 208 VAC, unless you
installed some kind of transformer to compensate.

I somehow think that the vendor of the motor made an error. Having 280
VAC sounds to me very unconventional, unless this was some kind of
special installation.

I would buy the motor. If in the even that it needed a higher voltage
because it lacks torque for your application, then there is the
possibility of needed an transformer. This would be expensive.

Some motors have a cover plate inside with strappings, to allow changing
its operating voltage, RPM, and direction of rotation.

If you were to run a synchronous motor on a lower voltage, it will have
lower torque rather than lower RPM, unless the supply voltage was
reduced to below the motor's stable operating threshold. Synchronous
motors are dependent on the AC frequency (Hz) for their RPM.

No, that's not true. It's 240V, the transformer has a grounded center tap so
120 from either side to neutral, and 240 between the hots. You find 208V in
commercial buildings and some apartment complexes that are fed with 3 phase,

If it's not a silly question, with the motor in question being offered "on

Nope. The NA standard residential voltage is 120/240 single phase. 120/208
only happens when the single phase power is derived from a 3 phase
wye-connected transformer bank. The only place I've heard of that happening
on a regular basis is in high-rise apartments.

For smaller buildings, the split delta configuration is more common. This
supplies 120/240 single phase and 240 three phase from one 3-transformer bank.
This is also sometimes known as the "wild leg" configuration because the leg
not associated with the single phase supply has a odd voltage to
neutral/ground. Something like 214 volts if my memory holds.

That's only true if the source transformer is a three phase WYE/star type.
If you have center tapped delta three phase, or single phase Edison split,
then you have genuine 240 volts (although with that delta you may also have
a third wire that is 208 volts relative to ground/neutral).

It may be a reference to working on 277 volts, which is an available voltage
in some large commercial/industrial locations.

I have a broken pool motor [magnetek y56y] which will cost a bundle to
fix
or repair.
While doing a search on the web, I found the same model (really cheap)
but
wired for 280V, instead of the 230 V load that my wiring is supplies.
Now, I was thinking of buying the cheap 280V model and installing it
instead. Aside from rotating at a different speed and
maybe some power inefficiencies, are there any other drawbacks of
using the 280V model
instead?
Yes-it could be toast in a couple of seconds. While motors with brushes,
like the ones used in short duty appliances, like drills and blenters, will
rotate slower in lower voltages, without problems, Asynchronous motors
(brushless) will really smoke to death if used in voltages significantly
lower than nominal. Can't you find a generic pool motor, if you know the
horsepower, voltage (3 phase? line to line) and intake and outlet gauge? and
maybe rpm?

HTH,
