burgermeister is correct. A 110V motor pulling 2 amps (110 x 2 = 220 watts) A 220V motor pulling half that (220 x 1 = 220 watts)
One of the major reasons higher voltages is used is to reduce the weight & cost of the motor, wiring and associated motor control centers. For example a 1000 hp motor would be HUGE if it were 110V due to the amount of copper needed & of course would weigh tons! The wiring would be as big around as your leg! However such large motors powered by 4000 V have copper feed wires the size of your pinky.
