Answer / Vijendra Sharma

The synchronous speed (N_s) of an induction motor can be calculated using the formula N_s = (120f) / P where f is the frequency in Hertz and P is the number of pole pairs. Given a stator frequency of 50Hz and a rotor frequency of 60Hz, it suggests that the motor has an uneven speed due to the difference in frequencies. However, under normal operation, the slip (s) would cause the rotor to run at a speed less than the synchronous speed. The exact speed would depend on the specific design and operating conditions of the motor.
