Synchronous Speed When Alternating current (AC) is applied to the stator of a three phase motor, a rotating magnetic field is setup. This rotating magnetic field moves with a speed called synchronous speed. The Synchronous speed can be calculated as follows: 120 times the frequency (F), divided by the number of poles (P): The synchronous speed decreases as the number of poles increases. The table below shows the synchronous speed associated with various numbers of poles at supply frequencies of 50Hz and 60Hz: Rated Speed. The speed of operation of an AC motor when fully loaded at rated voltage is called the rated speed.
Then by calculating average speed you actually calculate the slope of the distance time graph. that allows you to figure out distance travelled in a certain time. This only works when the accelleration is constant. then the average speed has the same value as the slope of the distance time graph.
