# 60 Hertz (Hz)

## What is 60 Hertz?

60 Hertz means the rotor of the generator turns 60 cycles per second, the current changes 60 times per second back and forth, direction changes 100 times. That means the voltage changes from positive to negative, and from negative to positive voltage, this process converts 60 times/second. The electricity 480V AC and 110V AC, are both 60 Hertz frequencies.

The speed of 60 Hz 2-pole synchronous generator is 3600rpm. AC power frequency is determined by the pole number of the generator p and speed n, freq. = p*n/120. The grid standard frequency is 60 Hertz, which is a constant value. For a 2-pole motor, the speed n = 60 * 120 / 2 = 3600rpm; for a 4-pole motor, the speed n = 60 * 120 / 4 = 1800rpm.

When the hertz 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 reduce 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 Hertz, 60 Hertz frequencies are appropriate.

### Why need a GoHz Converter for 60Hz to 50Hz?

Case 1: When we travel or move from one country (60 Hz, e.g. USA, Canada) to another (50 Hz, e.g. UK, Australia), and bring some electric appliances which are not compatible with running Hz, or sometimes we just buy a device which is only available for 60 Hz power system, in such cases, we can use a GoHz frequency converter to convert 60 Hz to 50 Hz, or the vice from 50 Hz to 60 Hz.

Case 2: Some global companies make electrical home appliances, industrial equipments outside the sales market country, e.g. a US company builds a factory in Malaysia (50 Hz) and tend to sell the products in USA, Canada (60 Hz), or a UK (50 Hz) company export electronic devices to US, Philippines, the company will need a GoHz converter to test the appliances' operation compatibility under expected Hz.

There are much more cases we need to convert 60 Hz to 50 Hz, or from 50 Hz to 60 Hz, in case you are interesting to get one GoHz frequency converter, just shopping on our web store, we are selling:
Single phase frequency converters, generally for home appliances;
Three phase frequency converters, generally for industrial machines.
