A squirrel cage induction motor is not selected when___________?
Correct answer: C. higher starting torque is the main consideration
- A. initial cost is the main consideration
- B. maintenance cost is to be kept low
- C. higher starting torque is the main consideration
- D. all above considerations are involved
Explanation
A squirrel-cage motor has low starting torque because its rotor resistance cannot be externally increased. Its low cost and minimal maintenance are advantages, so it is avoided when high starting torque is required.
