About 60Hz And 60Hz Machines

50Hz or 60Hz? The majority of power outlets across the world operate 50Hz (220–240 V), ranging from majority of Europe and Asia, Africa, Australia, Russia, and South-Southern America. However, Northern America, and Nothern South America, operate a frequency of alternating current at 60Hz (100–127 V). To most, this is not new information, but how many can actually answer- why the difference? When looking at the choice of grid frequency (assuming both voltage levels are the same), there can be seen to be no particular major advantages between either frequencies, with both being quite similar from an electrical perspective. Where they differ, however, is from a design perspective. Simply, 60Hz supplied to a motor makes it rotate faster compared to it being supplied by 50Hz. It used to be easy, insofaras machines with motors would be able to work on either 50 or 60Hz, however as electric motors have developed over the years to become increasingly efficient, it seems that they are also more fussy about the frequancy or the supply. These days a machine that can run on both frequencies is a rarity and it is typical that they either run on 50Hz or 60Hz, but not both.
