    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

    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.

    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.

    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!

    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
