An 8-pole, wave-connected armature has 600 conductors and is driven at Problem 1. 625 rev/min. If the flux per pole is 20 mWb, determine the generated e.m.f.

...

How are eddy current losses affected by the frequency and density of the flux wave?

A 6 pole wave wound d.c. shunt generator has 500 conductors. A generator delivers 50 kW of power at 250 voltage at full load. The resistance of the field circuit is 125 2. Actual brush shift is 10°. Then find the demagnetizing and cross magnetizing ampere turns per pole and how many additional turns must be wound on each pole to eliminate the demagnetizing effect.
