An induction motor X operating at the slip of 3%. An induction motor Y operating at slip of 40%.

A. Machine X is only stable

B. Machine Y is only stable

C. Both the machine X and Y are stable

D. Neither X nor Y is stable

I have been asked this question in an interview.

The doubt is from Induction Motor Phasor Diagram in section Induction Machines of Electrical Machines

Right option is A. Machine X is only stable

The best I can explain: Induction motor operates stable in the low slip regions as the losses are reduced.
