Calculation of Actual Speed:

- The synchronous speed of a 4-pole motor connected to a 50 Hz supply is given by:
Ns = (120 * f) / P
Ns = (120 * 50) / 4
Ns = 1500 rpm

- The actual speed of the motor is given by:
N = Ns * (1 - s)
N = 1500 * (1 - 0.04)
N = 1500 * 0.96
N = 1440 rpm

Therefore, the actual speed of the 3-phase 4-pole induction motor with a slip of 4% on a 50 Hz supply is 1440 rpm.
