Which of the following is not correct for squirrel cage induction motor?

  • A.Simple construction
  • B.Low power factor
  • C.High efficiency
  • D.Low cost

Answer: B

Low power factor is the statement that is not correct for a squirrel cage induction motor, according to the key. A squirrel cage motor has a simple, rugged construction, a high efficiency and a low cost, and these are the usual advantages given for it.

The power factor of an induction motor is in fact low on light load, so the statement is not wholly wrong, which makes the question arguable. The answer follows the key, and the second option is the one given.
