The two-pole machine has a field winding located on the stator and an armature winding on the rotor, with nf = 800 turns and na = 50 turns, respectively. it has a uniform air gap of 0.5 mm. the armature has a diameter of 0.5 m, and it is 1.5 m long. the field winding carries a current of 2 a. the rotor is driven at 3600 rpm.1) find the maximum flux linking one loop of winding.
2) find the frequency of the rotor induced voltage.
3) find the instantaneous voltage voltage induced in the rotor coil.
4) determine the rms voltage induced in the rotor coil.
