The electricity 480V AC and 110V AC, are both 60 Hz frequencies.The speed of 60 Hz 2-pole synchronous generator is 3,600 RPM. Thanks. In 1888, German physicist Heinrich Rudolf Hertz (Feb-22, 1857 to Jan-1, 1894), the first person confirmed the existence of radio waves, and had a great contribution in Electromagnetism, so the SI unit of frequency Hertz is named for him. I work in US manufacturing. It is different with variable frequency drive, which is special for motor speed control only, and also different with ordinary voltage stabilizer. This will require consultation with the OEM. A Variable Frequency Drive (VFD) can be used to properly address the issues associated when operating 50 Hz equipment at 60 Hz. Here are some of the major differences you should know about. You can use a 50Hz coil at 60Hz with no problem because 8.3mS + and 8.3mS - is a short time to grow then collapse magnetism. Frequency converter output is very close to the ideal power supply, hence, more and more countries use frequency converter power supply as a standard power source in order to provide the best electrical power supply environment for appliances to estimate their technical performance. Mechanical centrifugal forces will be 20% higher in case of 60 Hz (rotor winding retaining ring has to bear centrifugal force while designing). Would like info regarding photo cell chip control for messing with or delaying response when useing 220 vs 110 same cells and chip way slower response time for 220. Lower the frequency will be the iron losses and eddy current losses. Ideal AC power supply is stable frequency, stable voltage, resistance is approximately zero and the voltage waveform is pure sine wave (without distortion). I just bought a hifi audio amplifier from Japan. Not every country supplies power in quite the same way, especially when it comes to things like 50Hz vs. 60Hz. want to make portable Maser, I got 220v 50Hz 1800VA UPS and 220v 50Hz 1250W Microwave oven; for me when I'm going to buy any electrical equipment always I will choose a 220-240 V with 50-60 hertz appliances or power tools by looking the specifications. The general guidelines for operating 60 Hz motors on 50 Hz systems relate to the fact that the volts per cycle have to remain constant with any change in frequency. All rights reserved. In general, 60Hz systems tend to use more voltage for the domestic power supply than 50Hz. frequency i want dept answer how to work frequency. The motor would be able to produce rated torque at both 50/60 Hz frequencies only apply if the V/Hz ratio is constant, meaning that at 50 Hz the supply voltage would need to be 380 V and at 60 Hz the supply voltage would need to be 460 V. In both cases the V/Hz ratio is 7.6V/Hz. Biggest potential issue with transformers is going from 60Hz to 50Hz. If you are affiliated with this page and would like it removed please contact pressreleases@franklymedia.com. They’re both equally valid power supply standards, and whether you use one over the other will depend more on your circumstances rather than the pros and cons of either. From an overall perspective, we can't say 50Hz is better than 60Hz or not, there is no difference. Hz (Hertz) is the frequency unit of the vibration cycle time of electric, magnetic, acoustic and mechanical vibration, i.e. Current usage by country or region is given in the list of mains electricity by country. But in some cases, one frequency is preferred to the other, which is usually noted on the nameplate or within the manufacturer’s catalog. These standards refer to motors running slowly or faster depending on the appliance and in what country it is working. The new torque will be reduced by the lower voltage:  (220/480)^2 = 0.21 but the lower Hz will give time for the magnetizm to increase to bring the torque back up 60/50 = 1.20 therefore 0.21 x 1.20 = 0.25 times the original torque. However the optimum system is accepted as around 230V (wire size and power required versus safety). http://www.gohz.com/difference-between-50hz-and-60hz-frequency. Thank you! A variable torque load varies by the cube of the speed.
AC power frequency is determined by the pole number of the generator p and speed n, Hz = p*n/120. At 60 Hz, the rotor of the generator turns 60 cycles per second, the current changes 60 times per second back and forth, direction changes 100 times. To change between different power supply frequencies will certainly have an effect on efficiency, and may mean de-rating is necessary. For independent power equipment like ships, aircraft or isolated area like gas/oil installation, any frequency (like 400 Hz) can be designed based on suitability. Frequently, the delivery of 50 Hz products is such that an alternate course of action, utilizing 60 Hz products, is desirable. For example with 50 Hz, generator will be running at 3000 rpm against 3600 rpm with 60 Hz. Now that you have a basic idea of what 50Hz and 60Hz are, you’re probably wondering how they differ and whether those differences are significant. choose the product catalog of your country. The issue is magnetic saturation of the core.

That means the voltage changes from positive to negative, and from negative to positive voltage, this process converts 60 times/second. The more significant difference is that 60Hz systems usually use 110V (120V) or thereabouts for the domestic power supply, while 50Hz systems tend to use 220V, 230V etc. The primary difference between 50 Hz (Hertz) and 60 Hz (Hertz) is, well, 60Hz is 20% higher in frequency. Why do some countries use one type of Hertz over the other?

Frankly we are stuck to our system frequency, say 50Hz in India and Europe vs 60Hz in USA and Canada, We have no choice. Thanks a lot for information . Can we run the 4000 KVA YNyn-0 Transformer without connection of H.T Side Neutral Point with earth. It is more important to have a standard and stick with it. Some of our equipment is sourced from Europe. But with higher frequency, output of generator and induction motors will be higher for same size of motor/generator because of 20% higher speed. Machinery imported into the United States is often rated at an operating frequency of 50 Hz—unless engineered for operation at 60 Hz.. I live in Ireland. The speed of 50 Hertz 2 poles synchronous generator is 3000 rpm. For example with 50 Hz, generator will be running at 3,000 RPM against 3,600 RPM with 60 Hz. Motor speed is directly proportional to the operating frequency. Some equipment, like many computer power supplies, can work on voltages from 100 to 240. Do you think your frequency converter will give me more quality??? It is more important to have a standard and stick with it. pls. About appliances I choose auto volts (110-240 V ) with 50-60 hz it would be beter. As noted, the motor speeds will vary depending on frequency. If it is you can do that. For a generator or induction motor pump (in simple terms) it means 1,500/3,000 RPM or 1,800/3,600 RPM (for 60 Hz).

(If you apply smaller voltage the magnetizm grows slower to allow lower Hz).

What is advantage and disadvantage of 50hz over a 60 hz, Thanks..for this information..best wishs....abou ammar..sudan..khartoum..00249917246647. For example with 50 Hz, generator will be running at 3000 rpm against 3600 rpm with 60 Hz. Wiring a VFD to control single phase motor speeds, Difference between 50Hz and 60Hz frequency, Impact of 60Hz (50Hz) motor being used on 50Hz (60Hz) power supply, frequency converter to change 60Hz to 50Hz. The primary difference between 50 Hz (Hertz) and 60 Hz (Hertz) is simply that 60 Hz is 20% higher in frequency. This option is mostly used in North America and Northern South America with household electrical outlets. i have a 60hz motor that runs on 460v, and a 50hz motor that runs on 380v. This has the impact that house wiring needs to be twice the cross section for the 110V system for the same power.

This may include trimming the diameter of the fan wheel or impeller to provide the same performance at 60 Hz as the unit had at 50 Hz. As mentioned above, the rated voltage is 20% at 60Hz than it is at 50Hz. For a generator or induction motor pump (in simple terms) it means 1500/3000 RPM or 1800/3600 RPM (for 60Hz). The output difference at 60Hz is roughly the same percentage difference as well. A 50 Hz motor operating on 60 Hz will attempt to rotate at a 20% increase in speed. We have 240 AC. From 50Hz to 60Hz represents 20% more energy per second than the engine needs to transform and dissipate. There is little real difference between 50 Hz and 60 Hz systems, as long as the equipment is designed appropriately for the frequency. Only depend temperature so we do not use 60 Hz. for different countries. The lower the frequency, the lower will be the iron losses and eddy current losses. In my humble opinion, you need to contact the original manufacturer and see if they can provide guidance. At the end of the day, however, there are no major differences between 50Hz and 60Hz.
Hardly an issue of the appliances nowadays. Voltage is higher at 60Hz than at 50Hz however and increases by roughly 20%. 5) Can I run a 50Hz motor on 60Hz power supply? Frankly and this Site make no warranties or representations in connection therewith. I have a coil that the specs say 110 volt 28VA @ 50HZ.
