The synchronous speed of a 3 phase, 6 pole Induction motor fed from a 60 Hz supply is: Select one: A. 3000 RPM B. 1200 RPM C. 1000 RPM D. 800 RPM
Added by Amy A.
Step 1
The synchronous speed (\(N_s\)) in revolutions per minute (RPM) is given by the formula: \[ N_s = \frac{120 \times f}{P} \] where \(f\) is the frequency of the supply in hertz (Hz), and \(P\) is the number of poles. Show more…
