Both 50 Hz and 60 Hz have advantages, but there is not much difference in costs etc in the real world. Both systems remain very popular, if one system was much better than it would have replaced the other. 60 Hz permits of smaller and therefore cheaper transformers and generators, though the gain is small. 60 Hz gives less flicker on lamps.60 Hz increases losses by induction and capacitance. Transformers emit noise at twice line frequency, this is more obtrusive at higher frequencies. AC induction motors produce their rated torque based upon the ratio of voltage and frequency applied to them, then industry design specs say +-10%. So a 380V 50Hz designed motor is based on 380/50 = 7.6 V/Hz, but because of EU harmonization programs for the various countries, they are usually designed to accommodate up to 415V 50Hz, so up to 8.3V/Hz.
