Difference between 50Hz and 60Hz frequency | GoHz.com

AdvantagesUsageIssuesThe primary difference between 50 Hz (Hertz) and 60 Hz (Hertz) is, well, 60Hz is 20% higher in frequency. For a generator or induction motor pump (in simple terms) it means 1500/3000 RPM or 1800/3600 RPM (for 60Hz). Lower the frequency will be the iron losses and eddy current losses. Lower the frequency, speed of induction motor and generator will be lower. For example with 50 Hz, generator will be running at 3000 rpm against 3600 rpm with 60 Hz. Mechanical centrifugal forces will be 20% higher in case of 60 Hz (rotor winding retaining ring has to bear centrifugal force while designing). But with higher frequency, output of generator and induction motors will be higher for same size of motor/generator because of 20% higher speed. The design of such magnetic machines is such that they are really one or the other. It may work in some cases, but not always, and to change between different power supply frequencies will certainly have an effect on efficiency, and may mean de-rating is necessary. There is little real difference between 50 Hertz and 60 Hertz systems, as long as the equipment is designed appropriately for the frequency. It is more important to have a standard and stick with it.Get price
