The low power factor of induction motor is due to___________?
Correct answer: D. all of the above
- A. rotor leakage reactance
- B. stator reactance
- C. the reactive lagging magnetizing current necessary to generate the magnetic flux
- D. all of the above
Explanation
The dominant cause is the lagging magnetizing current needed to establish air-gap flux; stator and rotor leakage reactances also add reactive effects. Thus all the listed factors contribute to the motor's low power factor.
