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. how to set minecraft server ipWebFeb 6, 2024 · For the metric measure of 609.6 m/s, multiplying by 1000 gives 609.6 x 1000 = 609,600 mm/s. 4 Divide by the result by the length of the twist rate.
