Q. The starting method for a 3-phase squirrel-cage induction motor which is inferior in view of poor starting torque per ampere of line current drawn is?

  • (A) series-inductor method of starting
  • (B) direct-on-line starting
  • (C) auto-transformer method
  • (D) star-delta method
πŸ’¬ Discuss
βœ… Correct Answer: (A) series-inductor method of starting
Explanation: due to inductor method, reactance increases and the starting torque decreases.
