Answer the question 4. Please.

3. A 3-phase, 4-pole, 230-V wound rotor induction motor (WRIM), has both its stator and rotor connected in wye. The rotor has half as many turns per phase as the stator. If the rotor is turning at 1725 rpm, determine: a. Slip in decimal and in per cent b. The blocked-rotor voltage per phase The rotor voltage per phase at the specified speed d. The rotor voltage between slip ring terminals (open-circuit conditions assumed) The rotor frequency at operating speed С. е. f. Calculate the rotor current per phase if R, = 0.075 ohm and Xbr = 0.375 ohm. 4. Using the motor in problem number 3, calculate the following: а. Rotor power input per phase b. Rotor copper losses С. Rotor power developed in kW d. Rotor power developed in Hp.
