50 Hertz Appliances

rselectric1

I have a potential client who wants to bring her washer & dryer from overseas. I think the appliances run on 50 hertz. I told her I would need to check with the manufacturer to see if running them here would be persmissable. I am guessing not. I meet with her tomorrow (10/3)
Any thoughts on this?

Tell her it hurts you to inform her they won't work

Could be. I know the cord will have to be changed to a NEMA plug too.
I cant imagine why they would want to ship them all the way over here.

Sell her a frequency converter.

Thanks Sparky-I've never run across this before. Will the supply house usually carry these?

Just looked up a Bosch washer from the UK:

Nominal voltage 220-240 V, 50 Hz
Nominal current 10 A
Nominal power 2,300 W

OK sparky, I think you got me. I followed your advice and did a little research and I think you know the result. But I may still try to sell her one!

Maybe the "whole house" model

Motors are typically designed for a specific frequency:

Even if you convert the voltage... it's still not a good idea.

Not unless they're from Japan where many appliances are made 50/60Hz due to the fact they use both frequencies domestically. Even then, induction motor equipped appliances rated for 50/60 Hz don't always perform the same. Refrigeration machinery provide less power. Other devices might work just fine, but require changing belt positions.


Microwave ovens, things with induction motor and alarm clocks(many don't have crystals, they use power line as time base) are typically frequency specific.
