What is the formula for synchronous speed?

What is the formula for synchronous speed?
Answer : The formula for **synchronous speed** (\(N_s\)) of an electric motor is given by: \[ N_s = \frac{120 \times f}{P} \] Where: - \(N_s\) is the synchronous speed in **RPM ( ... s the theoretical speed at which the motor's rotor would rotate if there were no losses, such as friction or slip....
