Extracted text: Q1 (а) With aid of suitable diagram, explain the losses and power-flow of an induction motor. A three-phase, 50 Hz, six pole induction motor runs at a no-load speed of 915 r/min. and full-load speed is 870 r/min. (i) (b) Calculate the slip of the rotor at no-load and full-load conditions. (ii) Based on Q1(b)(i) results, calculate the electrical frequency of the rotor at no-load and full-load conditions. (iii) Calculate the speed regulation of this motor.
