Often, most electronic devices can operate at 50 or 60 Hz. This is due to motors working either faster or slower than they were designed.

Getting this right is critical, as you need to ensure that you have the voltage to support your equipment choices. All else being equal, a three-phase piece of equipment will be more efficient to run than a single-phase unit.
Amps Amp, short for ampere, measures the strength of a current of electricity. Go back to the waterpik analogy. We equated the volume of water traveling through and shooting out of the waterpik to electric current. The strength of this water aka current is measured in amps. To operate, equipment needs to draw a certain amount of amps from a circuit. On the flipside, equipment puts an amp load on a circuit.
Therefore, before you order equipment, you need to ensure that your equipment does not demand more amps than your circuit can handle.
In other words, if you have a amp circuit, you need to order an 8-amp unit or lower. Watts Watts are a measure of power. Watts are a measurement of the amount or more specifically the rate of energy or power released or used. Again, water makes for a good analogy. If a stream of water is used to turn a water wheel, a certain amount of power or energy is produced and then used by whatever the water wheel is supplying power to.
Watts measure the derived power, or the rate of production or use of this energy. When it comes to cooking, watts are a big deal. The higher the watts you can derive — the more output and speed you can achieve in the kitchen. Again, amps multiplied by volts equal watts. Take induction cooking equipment from Hatco for example. You can choose from , , and watt units. When the frequency increases, the copper and steel consumptions of the generator and transformer decrease, along with the reduction of weight and cost, but will make the inductances of the electrical equipment and transmission line increase, reduce the capacitances and increase losses, thereby reducing the transmission efficiency.
If the frequency is too low, the electrical equipment's materials will increase, along with heavy and high cost, and will make lights flashing obviously. Practices have proved using 50 Hz and 60 Hz frequencies are appropriate. 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 times.
The speed of 60 Hz 2-pole synchronous generator is 3, RPM. AC power frequency is determined by the pole number of the generator p and speed n, freq. The grid standard frequency is 60 Hz, which is a constant value. It is different with variable frequency drive, which is special for motor speed control only, and also different with ordinary voltage stabilizer.
Ideal AC power supply is stable frequency, stable voltage, resistance is approximately zero and the voltage waveform is pure sine wave without distortion.
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. The lower the frequency, the lower will be the iron losses and eddy current losses.
Lower the frequency, speed of induction motor and generator will be lower. 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. 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 Hz and 60 Hz systems, as long as the equipment is designed appropriately for the frequency. It is more important to have a standard and stick with it.
The more significant difference is that 60 Hz systems usually use V V or thereabouts for the domestic power supply, while 50 Hz systems tend to use V, V etc. This has the impact that house wiring needs to be twice the cross section for the V system for the same power.
However the optimum system is accepted as around V wire size and power required versus safety. It is no big difference between 50 Hz and 60 Hz, nothing is bad or good basically. To obtain optimum performance, motors used for 50 Hz applications should be specifically engineered and manufactured for 50 Hz.
Frequently, the delivery of 50 Hz products is such that an alternate course of action, utilizing 60 Hz products, is desirable.
