TRANSFORMER IS A STATIC DEVICE.THERE ARE NO MOVING PARTS IN
IT.THERE WILL BE ONLY MAGNETIC COUPLING IS THERE BETWEEN
PRIMARY AND SECONDARY.POWER WILL BE TRANSFERRED BY FLUX
LINKAGE.

Answer / krishna

transformer is work on principle of electro magnetic
induction.power will be transfered by flux linkage between
primary and secondary.and there have not any rotating
device.and transformer not work any mechanical work it only
transfer the power.

Answer / naveen joshi

Transformer are working on Mutual Induction ,as we know 
alternating current generate Fluctuating magnatic field on 
primary side that's why Current and Voltages Induced in secondary side of Transformer(No need of rotation either part).
