A two-pole synchronous machine is carrying balanced three-phase armature currents ia = v2 la cos(ot), ib = v2 Ia cos(@t-120) , ic = v2 la cos(@t-240) The rotor is rotating at synchronous speed m, and the rotor direct axis is aligned with the stator phase-a axis at time t= 0. Find the direct- and quadrature-axis current components.
