The pole arc of the rotor is an and the smaller airgap is 9min. If the effective airgap over the interpolar space is assumed to be infinite (9max →∞) and the winding functions of the stator coils are given by, Ns1 Nas = cos(p) 2 And the winding functions of the rotor coils are: Nar1 2 Nar Nbs=121 cos(-²7) 3 Narı 2 = Nar Ncs = = Ns1 2 sin(0₁ - 0) cos(0, - $) For a transformation in the rotor reference frame T(0r): a) Derive the stator magnetizing inductances Ldsds, Lasqs, Lnsns. b) Verify that the stator mutual inductances Ldsqs, Lasns, Lnsds are zero. c) Derive the stator to rotor mutual inductances Ldsdr, Lqsqr, Ldsfr. Verify that the rest are cos+ s(ø Nfr1 2π 3 Nfr = 2 sin(0, - ) zero. d) Derive the rotor magnetizing inductances Ldrdr, Lqrqr, Lfrfr. e) Derive the rotor mutual inductances Ldrqr, Lqrfr, Lfrdr. Hint: use MATLAB symbolic math toolbox. You can use any commands including syms, subs, simplify, and int. bs' cs-axis dr as' as dr dr-axis fr - axis bs cs' (0) gr-axis as - axis The pole arc of the rotor is an and the smaller airgap is 9min.
