WebDec 26, 2024 · If a motor has four poles it will rotate half a revolution per mains cycle. At 50 Hz this will be 50 x 60 / 2 = 1500 RPM. 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. black pink news
