Define synchronous speed and slip 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....

What is slip and formula?

What is slip and formula?
Answer : In the context of electric motors, particularly **induction motors**, **slip** refers to the difference between the speed of the rotating magnetic field (synchronous speed) and the actual speed of the ... any mechanical power, while at low slip (close to 0%), the motor is operating efficiently....
