A three-phase, six-pole, 60 Hz, 230-volt wound rotor motor has its stator connected in delta and its rotor in star. There are 70 percent as many rotor conductors as stator conductors as stator conductors. Calculate the voltage and frequency between slip rings if normal voltage is applied to the stator when, a, the rotor is at rest, b. the rotor slip is 0.04
