Web15 nov. 2014 · When selecting a three phase motor, the number of poles is chosen to achieve the speed of rotation that you require. Here are two tables, one for a 50 Hz power supply and one for a 60 Hz power supply: The formula is n = 60 x f where f. For a 50 Hz three phase supply: 2 poles or 1 pair of poles = 3,000 RPM (minus the slip speed = … WebThe Inductive kick effect can be used to best effect with a synchronous rotary spark gap because the time at which the spark gap fires can be adjusted to obtain the desired voltage gain (and power throughput.) The graph below shows the effect of adjusting the point at which the sync rotary fires. The normal open-circuit voltage of the ballasted ...
