A round rotor electrical machine having 2 poles (2p-2) and 3 phases with a regular air-gap has distributed windings and air gap MMF is sinusoidal. Stator windings (a,b, and c) are located at stator with a 120° geometric difference. Self inductance of all windings are L., mutual inductances between Phase a, b and c windings are L L and L. There is only one winding on rotor with a constant self- inductance of Le. Mutual inductances between rotor winding and a,b and c windings are as follows. e Laf = Lcose Lay L. cos(0-120°) Lef = L. cos(0-240°) Phase c axis Rotor winding axis 8-at+8, Phase a axis Phase b axis e is the angle difference between the phase a winding and rotor winding. (0=x+6) Winding currents are i,(t)=cos(t), is(t)=l,cos(xt-120") ve i(t)=l,cos(est-240°) and ink. Rotor is set free. Magnetic circuit is accepted to have no-loss. All winding resistances are neglected. Write Inductance matrix [L] Obtain Flux Linkage equation [2] Write voltage equations [va(t), va(t), v.(t), vi(t)]
