Question:

For the following two machines P 2 MW, Vine 3300V Machine 1: A round-rotor synchronous motor with a wound-rotor field has the following parameters: R is negligable,x,-. 4.57 Ω at ae-: 2π50 rad /s Machine 2: A salient pole rotor is designed for the same stator yielding the following motor parameters. R is negligable, Xd-1.3 ถ. Xq-4.57 Ω at ae 2n50 rad /s Find a) Find the back-EMF voltage E, current I, and torque angle o for both machines at the rated power, voltage and speed with unity power factor b) If machine 2 is excited with the rated current, determine the maximum motoring torque and the corresponding current angle c) Find the current I and power factor pf at rated power if Machine #2 is operated as a reluctance machine (E-0) with rated voltage excitation at rated speed.
