A 3000V 3-phase synchronous motor running at 1500rpm has its excitationkept constant corresponding to “NO LOAD” terminal voltage of 3000volts. Determine the power input, power factor and torque developed for an armature current of 250Amp.If synchronous reactance is 5ohms phase and armature resistance is neglected.
