Detailed Solution
Download Solution PDFConcept:
The synchronous speed of a synchronous machine is given by
\({N_s} = \frac{{120f}}{P}\)
Where f is frequency and P is the number of poles.
A synchronous machine always rotates at a synchronous speed.
Calculation:
Number of poles (P) = 8
Frequency (f) = 50 Hz
Synchronous speed, \({N_{s}} = \frac{{120 \times 50}}{8} = 750~rpm\)
