What is the relation of the rotor resistance to efficiency and losses?
(a) as rotor resistance, losses increase, efficiency increases
(b) as rotor resistance, losses increase, efficiency decreases
(c) as rotor resistance, losses decrease, efficiency has no change
(d) as rotor resistance, losses decrease, efficiency decreases
I got this question in exam.
The doubt is from Design of Rotor Bars and Slots topic in chapter Three Phase Induction Motor of Design of Electrical Machines
