Electrical Induction Motors - Synchronous Speed

Calculate the synchronous speed of an induction motor based on power supply frequency and number of poles. The synchronous speed is determined by the formula: n = f (2 / p) 60, where n is shaft rotation speed (rpm), f is frequency (Hz), and p is the number of poles.
