What losses occur in the teeth of dc generator?(a) To reduce hysteresis loss(b) To reduce eddy current loss(c) To reduce eddy current as well as hysteresis losses(d) To achieve high permeabilityI got this question in class test.My doubt stems from Operating Characteristics of DC Generators topic in section DC Generators of Electrical Machines

Answer»

Right choice is (c) To REDUCE EDDY current as well as hysteresis LOSSES

Explanation: Teeth of the MACHINE has both eddy current losses as well as hysteresis losses.
