Extracted text: 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 a. Slip in decimal and in per cent rpm, determine: 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 C. е. f. Calculate the rotor current per phase if R, = 0.075 ohm and Xpr = 0.375 ohm.
