there are a transformer and a motor. both are connected to 3phase, 415 Volt, 50Hz power supply. Both are working with induction principles. Then, why, motor is rotating and transformer is not rotating.

We know that primary transmission is done to reduce current so that i^2*r loss could be minimised but according to ohm's law v is directly proportional to i,which indirectly means higher potential difference means larger current?so how the current is minimised in high power transmission line??
