280V motor on 230V circuit         


Author: Deodiaus

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?

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.

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...

You mean the 120/208 VAC motor that was for sale on Ebay?

are you sure it isn't 208 ?

I'd be suspicious that the 280V was a misreading somehow of 230V.

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.

280vac is an odd rating, so it 230. 120/240 is standard single phase
ratings. 208 is three phase. If it's 208 don't get it.
