50hz appliance on a 60hz net
|
|
|
| hello there,
i wonder if it is worth to take the laundry machine i bought in france
(220/230V 50Hz) back home to brazil (220V 60Hz). will the different
frequency damage the appliance? as far as i understood there's no
converter for the frequency.
thx
p.

Ask the manufacturer, either by post, email or phone. Other people can
guess, some can make an educated guess - but it still will be a guess.
My guess is that it wouldn't last long, even if it did run. Motors in
such units tend to be made to a price and have short enough lives even
at the right frequency.

Most european washing machines use Universal motors because
of the need for complex speed control, and these won't care
about the mains frequency. If the machine has a mechanical
timer/controller, then the timed parts of the cycle would
be 20% shorter.

With the motor running at line frequency the product rpm x time would be
the same :-)

| Check with the manufacturer. The EU has standards. Follow there
recomendations. Perhaps you can work a trade-in in Brazil. Some of these
manufacturers have world-wide distribution. If you are still in France.
Check with the dealer there first. No since shipping the thing to Brazil if
its not worth the freight.

How much does it cost to ship a single unit? Hint: it's a lot more than it
costs for the manufacturers to ship a whole boat load (literally) full from
wherever they make them. Compare that cost to buying a proper unit back in
Brazil, hopefully of the same manufacturer, vs. the resale in France. Add
in the cost of crating it properly for the voyage, plus insurance or risk of
damage.
Personally, I would not have considered it worth it enough for anything I
cannot personally pick up and carry for myself ... to even get to the point
of working the numbers.
For a clothes dryer, there is a specific rotation speed needed for the drum
and the motor is usually an inductive type that depends on the frequency.
However, I am told by someone that sells multi-standard appliances in the
USA, that many dryers have two positions for a belt drive on the drum and
motor with one belt position for 50 Hz and one for 60 Hz. Presumably the
motor can handle either frequency in such a design. If you have a separate
dryer, you might check into this.

But if moving permanently, as my brother-in law did some years ago*, all
your belongings go into a standard container. I then doesn't cost any more
to add a washing machine.
He's still in Canada 30+ years on,

Not with a Universal motor for the drum.

You don't crate up the heavy stuff inside the container? I'd think if
stuff shifts around, the heavy stuff will crunsh the other stuff.

| hi all,
thanks a lot for all your comments. there's a chance i'd have to hire
a container to send my other things anyway, and (only) in that case
i'll consider to take the wash/dryer machine with me. i still didn't
get a good answer from the manufacturer about this issue, but i will
keep trying... this kind of appliance is amazingly more expensive to
buy in brazil (i'd like to understand why, sometimes they can be 3
times more expensive the same model) that's why i consider taking it.
but if i manage to send/carry the other things without a container,
then i will just resell...
p.
