Question

What is the range for the ratio of the resistance to reactance in the split phase motors?

(a) 0.40-0.55

(b) 0.45-0.55

(c) 0.45-0.8

(d) 0.45-0.6

This question was addressed to me in an online quiz.

This intriguing question comes from Design of Rotor topic in division Design of Single Phase Induction Motor of Design of Electrical Machines

Answer 1

Right option is (b) 0.45-0.55

The best I can explain: The range for the ratio of the resistance to reactance in the split phase motors is 0.45-0.55. The range for the ratio of the resistance to reactance in the capacitor start motors is 0.45-0.8.
