Frequency Formula - What is Frequency Formula?
WebDec 26, 2024 · If a motor has six poles it will rotate one third of a revolution per mains cycle. At 50 Hz this will be 50 x 60 / 3 = 1000 RPM. This can be generalised as RPM = 120 x f / poles. Therefore # of poles = 120 x f / RPM. Since induction motors slip the full-load RPM will be somewhat less than the calculated speed. Webfrequency, in physics, the number of waves that pass a fixed point in unit time; also, the number of cycles or vibrations undergone during one unit of time by a body in periodic motion. ... Frequency is usually expressed in the hertz unit, abbreviated Hz. One kilohertz (kHz) is 1,000 Hz, and one megahertz (MHz) is 1,000,000 Hz. In spectroscopy ... hua mulan 2009 reparto
