A four-pole synchronous AC generator with a smooth air gap has a distributed rotor winding with 260 series turns, a winding factor of 0.935, and an air gap of length 0.7 mm. Assuming the mmf drop in the electrical steel to be negligible, find the rotor-winding current required to produce a peak, space-fundamental magnetic flux density of 1.8 T in the machine air gap.

Problem 1: A four pole, 60Hz, 3-d synchronous generator has a rotor radius of 15 cm, a rotor length of 2.7m, and an air gap length of 2 mm. The rotor field winding consists of 1000 turns with a winding factor of 0.962. The Δ connected armature winding has 25 series turns per phase with a winding factor of 0.935. The generator is designed to achieve rated open-circuit voltage at a peak air-gap flux density of 1.25 T (a) At...
