By using step-down transformer
if you drove the 18V winding with 230V the transformer would burn out, if it didn't catch fire first
no, the transformer is much more efficient <><><> HOWEVER- a transformer only changes the voltage of AC current- it does not change it to DC. You will still need diodes or rectifiers. You can also use a motor/generator- a 230v AC motor turns a 12 v DC generator.
You need a step up transformer unfortunately. Buy an Ugly's book electrical reference book. They're great and there is a transformer chart in there that will list the proper size or Kva that you will need according to your amperage need.
since the iron loss depends only on the volage and frequency,the supply volage is 230v ac.Hence iron loss is always constant
You can get a transformer that converts the UK's 230V power to 120V, but you cannot get a transformer that will convert from 50Hz to 60Hz. Often, US equipment can work, except that they will work hotter and less efficiently on the 50Hz power. Consult your clipper and trimmer documentation - you may find that it will work just fine on 50Hz.

NO
The higher voltage it transformed to a lower voltage by the use of a step down transformer.

If you exceed the rated voltage of your transformer, there is a high possibility that its insulation will break down and you will ruin that transformer.
You can use a voltage converter or transformer to change 115V to 230V. Make sure to select a converter or transformer that is capable of handling the required voltage conversion and power load. It is always best to consult a professional electrician for safe and proper installation.
It is not advisable because the motor would run 20% faster which might produce damaging overpressure in the thermal circuit.

If you mean in domestic use, the US is at 120 V and the UK at 240 V. So you need a transformer with a 2 to 1 turn ratio, to step up if using a UK appliance in the US, or to step down if using a US appliance in the UK.
Using Ns=(Np*Es)/Ep =(500*12)/230=26 turns
