Which option is false regarding a single-phase induction motor?
- 1The capacitor-start induction motor differs from the resistance-start induction motor during the starting period only.
- 2The line current during starting of a resistance-start induction motor is found to be two-thirds lower than the starting line current of a corresponding capacitor-start induction motor.✓
- 3The starting torque of a capacitor-start induction motor is significantly higher than that of a resistance-start induction motor.
- 4The starting torque of a resistance-start single-phase induction motor is 1.5 to 2 times the full-load torque.
Correct answer
The line current during starting of a resistance-start induction motor is found to be two-thirds lower than the starting line current of a corresponding capacitor-start induction motor.
