(a) A four-pole three-phase induction motor operate at 50-Hz. It has the no-load speed of 2940 rpm and the full-load speed of 2860 rpm. (i) Calculate the motor speed. (ii) Calculate the motor no-load slip and the electrical frequency of the rotor. (ii) Calculate the motor full-load slip and the electrical frequency of the rotor. (iv) Determine the speed regulation of this motor.
