Revolving Field Theory:
Revolving field theory is a theory that explains the operation of single-phase induction motors. According to this theory, the stator winding produces a magnetic field that rotates around the stator at a constant speed. This magnetic field induces a current in the rotor, which in turn produces a magnetic field that tries to follow the rotating field of the stator. Due to the relative motion between the two fields, torque is produced, and the rotor starts to rotate.
Forward and Backward Frequencies:
The forward and backward frequencies of the rotor emf of a 4 pole 50 Hz single phase induction motor when running at 1300 Rpm in the same direction of the forward field can be calculated using the following formula:
f_r = (120 * n_s) / (p * 2)
Where:
f_r = rotor frequency
n_s = synchronous speed (in RPM)
p = number of poles
For a 4 pole motor running at 1300 RPM, the synchronous speed would be:
n_s = (120 * f) / p
n_s = (120 * 50) / 4
n_s = 1500 RPM
Therefore, the forward frequency of the rotor emf would be:
f_r (forward) = (120 * 1500) / (4 * 2)
f_r (forward) = 2250 Hz
Similarly, the backward frequency of the rotor emf would be:
f_r (backward) = (120 * 1300) / (4 * 2)
f_r (backward) = 1950 Hz
Conclusion:
In conclusion, the forward and backward frequencies of the rotor emf of a 4 pole 50 Hz single phase induction motor when running at 1300 Rpm in the same direction of the forward field are 2250 Hz and 1950 Hz respectively.
