A 10-pole lap-wound generator is rated at 120 V, 500 A, and 750 rpm. The armature has 163 slots with 4coil sides per slot and 2 turns per coi1. The hot winding resistance is 7.2 mQ, and the brush contact drop is 1.5 V.a. Find the rated load power, the developed torque, and the flux per pole; also find the per coil and per turn resistances and emfs.b. The armature coils are reconnected to form a simple wave winding with the speed and flux per pole unchanged. Find the new machine ratings. (current, voltage, power)d. For both lap and wave connections, find the average voltage between adjacent .commutator segments
