The formula to calculate the Synchronous Speed (Ns) is:
\[ N_s = \frac{120 \cdot f}{n} \]
Synchronous speed is a definite speed for an alternating-current machine that is dependent on the frequency of the supply circuit. It is measured in Radian per Second.
Let's assume the following values:
Using the formula:
\[ N_s = \frac{120 \cdot 54.6}{4} \approx 1638 \]
The Synchronous Speed is approximately 1638 Radian per Second.
