Why The voltage in the us 110v60Hz is different from european 2250Hz?
Realpontiacman is partly correct. However, the peak voltage in the sinusoidal waveform he described is actually square root of two (1.414) times the nominal 220 volts, or 311 volts. This is because the nominal voltage is what is known as a root mean square (rms) average. If you were to take the sine wave (actually the absolute value of the sine wave) and level it out, you get the rms value. The rms value is used in electrical calculations instead of the peak value because it gives a true representation of the power transmitted. Also, the voltage won’t affect the amount of wear and tear on a motor. It just determines the number of turns in the motor windings. A particular magnetic field strength is needed to start and run a motor. The higher the voltage, the fewer turns needed in the electromagnet. The frequency may affect motor life, I’m not sure. 50 Hz motors run slower than 60 Hz motors, and may last longer because they haven’t rotated through as many revolutions. The most significan
