Using a Transformer on 220 v Appliance

[Butter]

I've got a girlfriend in the Philippines who wants this fancy
Kitchenaid Mixer that cost a fortune. They hae 220 over there but
these mixers if I buy here are much cheaper. Its that the cheaper ones
are made for 110 volts. Everywhere i see about these it says using a
transformer won't work and I can't think of any reason this is true.
So i'd like some help on where I can get the 110 for only $200( plus a
transformer) here or pay $400 for the 220 volt
rosco

probably reason why they say that is thier boss told them not to make
promises they don't understand.

the domestic 110V supply in your house comes from a transformer out on
the street somewhere.

unless the frequency of the mains is important using a large enough
transformer will work. most motorised kitchen appliances have (noisy)
universal motors and these motors don't need a specific AC frequency.

on the boilerplate of the appliance it should sat how many amps the
appliance needs, multiply that figure by the voltage (115) to get
the minimum VA rating for the transformer.

Could it be something to do with using a rectifier to reduce the speed, with
the danger that the resulting DC component of the current could saturate a
small transformer and start a fire?

By the time you pay for the transformer large enough to operate that

and the shipping to get that and the mixer to that country, you'll be
better off just getting her that 220 model with the price at hand.

Its cheaper to pay the $400 bucks!.

FWIW, the Phillipines uses 60Hz.

Who mentioned RECTIFIER.

There is no rectifier in a simple transformer, and no imaginable problem if
the transformer is big enough and of the correct ratio.

That said, the OP should just buy one local and forget the hastle.

Did I say there was a rectifier in a transformer? Duh.

You appear to be unaware that one of the cheap methods of reducing the speed
of a universal motor is to connect it to the AC mains via a rectifier ...
and that's a separate part rectifier. So my question stands.

If you use a real transformer it will work, but a real transformer might
be more expensive than the unit. Probably they're using "transformer" to
refer to some voltage-limiting circuit that munges up the waveform of
the mains, which messes with the speed controller's brain.

Here's how to tell: If you can lift it with one hand, it's not a true
transformer.

Or, you might try a 220V triac lamp dimmer set at half, but that would
have to be tried. It could be tested in the US on the 240V that's
available between the black and red wires.

Good Luck!
Rich

By the time you pay for the transformer large enough to operate that
and the shipping to get that and the mixer to that country, you'll be
better off just getting her that 220 model with the price at hand.

Its cheaper to pay the $400 bucks!.

When I was in Thailand in the 1970's I got a 220-110 autotransformer
for about fifteen bucks.

She might be able to find something like that at a surplus shop.

Cheers!

I'm afraid this is the conclusion I've come to also. All this money

for some silly Food Toy. Its
$400 and I'm afraid to ask shipping

Why not find a place that sells them in the Philippines, but it online
and have them deliver it to her?
