I bought a 110V to 220-240V transformer to try and run a UK (230V) juicer. The existing output won't turn the motor so how do I get the output that appears to be 220V up to 240V?
My physics reminds me that I need to lower the resistance somehow but without getting a new motor how can I do that?
An y help would be most appreciated.

Stepping up the voltage steps down the current, these two factors equal the power. You will have to run a 240v ckt. with 2 hot legs and a ground. That must be one humungus juicer.

If it really is a 110V to 220-240V transformer, it will have a different set of connections to get the different secondary voltages. If there is only one set of primary and one set of secondary connections, there is no changing the voltage. You also need to make sure you have a transformer with a volt-amp rating greater than the wattage of the juicer. For example, a 500VA transformer won't power a 1000watt appliance. Even with the correct voltage, one of the two devices will eventually fail.

Sounds like your transformer is underated for the motor. There is no way to modify it. Before panicking however, be careful that you are not using an anemic extension cord for either the input or output. Try using one of higher guage, which will decrease the resistance and help the output. If that is not the case, then you have bought too puny a transformer.

chances are its because your frequency is wrong (if you are in N. America), being its a UK appliance. you are trying to put 60Hz into something im pretty sure was designed for 50Hz. it should still work even if your transformer was only putting out 220V. you may want test the output of the transformer with a multimeter to make sure its working properly as well.

most likely problem is the kva or va rating of the transformer is not high enough to run juicer....to figure the va you multiply the volts times the amps...so if the juicer is 240 volts at 4. amps that would be 240times 4 =960 watts or va...it would take a 1kva transformer to drive the juicer used in the example...the amps and volts used should be on the nameplate of the juicer...

There's either something wrong with your motor or your tranformer isn't rated for enough kwatts. A motor rated at 230V will run just fine on 220V.
