Q10. The rotating machine of Figure Q10 has the following parameters: Lss = 0.18 H, L = 0.06 H, and Lsr = 0.079 cos 0 H. The system has two current sources available for its windings. The windings are supplied with either of two sources: source A = 2.5 Ade; source B = 8.5 Arms, f= 50 Hz. The rotor is free to turn about its axis and the position of the rotor at any instant is 0 = @t +8, where Om is angular velocity of the rotor and & is the rotor position at t = 0. Determine the torque developed at om = 100r rad/s and for the following source connections: (a) Source A to both windings (b) Source B to both windings (c) Source A to the rotor and source B to the stator.
