Question

The electrical anlogous of the mechanical load in the induction machine is given by?

(a) (r2)*(1-s)/s

(b) (r2)

(c) (r2)/s

(d) (r2)/(1-s)

This question was addressed to me in semester exam.

The doubt is from Equivalent Circuit in chapter Induction Machines of Electrical Machines

Answer 1

Right answer is (a) (r2)*(1-s)/s

The explanation: Mechanical load is represented by a factor (1-s)/s of the rotor resistance.
