A 150 kW, 3000 V, 50 Hz, 6 pole, star- connected three phase slip ring induction motor has the following parameters referred to the stator: R'2 =1.30 X'2 =14.7 Q The stator impedance may be neglected. The transformation ratio is 3.6 (stator/rotor). With the aid of the diagram, propose the solution to reduce the starting torque by reducing the starting current. Calculate: The starting current and starting torque on rated voltage.
