| 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.
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.
