Extracted text: (13) For a certain polyphase induction motor, which at full load operates at its maximum power factor, the starting current and the no-load current at full voltage exceeding the full-load value. What would be the power factor and slip at full-load reduction in voltage which would just permit stable operation at a torque not Assuming the rotor and stator copper losses are equal, determine the percentage are in the ratio of 10/1 and the power factor in each case is 0-25. torque with the voltage thus reduced?
