What happens if a 60Hz motor is driven at 50Hz? The voltage is the same. The motor would be running at a lower speed, about 20 % less RPM. Unless the motor was designed with more than just enough iron, it may saturate, and overheat, maybe even burn if thermal (current) protection does not trip it.6 oct. 2021
In many cases an appliance made for 220 volts 50 hertz will work fine at the same voltage but 60 hertz. Some motors may be a bit weaker in the 60 Hz grid, but usually the design has big enough margin of safety that this should not matter.
Which is faster 50Hz or 60Hz?
Speed. For most standard motors, the RPM is proportional to the frequency, which means there is a speed increase when you use 60Hz versus 50Hz. In fact, 60Hz can be up to 20% faster.3 déc. 2019
What is the difference between 50Hz and 60Hz motors?
60Hz systems, at same Voltage and Amperage, produce 20% more energy than 50Hz systems; for that reason, 50Hz systems will have a higher output of voltage, amperage or both, to compensate.
Operating Speed
60 Hz is 20 percent higher than 50 Hz frequency, which is the biggest difference between the two. Different sizes of frequency converters may affect overall performance. When machinery, such as generators or induction motor pumps, uses lower frequency, it prevents iron loss.
