Voltage and Frequency Transformer
« on: October 18, 2016, 03:51:34 am »
I have kitchen equipment which runs on US standard of 110v at 60hz while I live in Australia with 220v at 50hz. Most of them have motors which are not rated for 50hz and some of the machines take around 700 watts.. I was wondering if there was any easy solution to convert both the Voltage and the Frequency preferably in a single and relativity cheap unit?
Thanks

you can run regular 120v 60hz induction motors at 100 volts, 50hz.

you can probably get away with running them at 120v, and certainly 110v is fine at, 50hz, but for largish motors 120v 50hz is too much.

most refridgerators compressors should be fine at 120v 50hz because the motor is small enough, that the extra volts won't saturate it much more than it already is, but if the line amps are more than 20% more than they are in the states on 120v 60hz i would drop the voltage.

that said most kitchen equipment is series wound motors.. mixers, electric knives, blenders. the frequency for these things does not matter. anything with a heating element won't matter either.
