Electrical Engineering XYZ MCQs
Which of the following induction motor has the highest starting torque:
- Squirrel cage induction motor
- Slip ring induction motor
- Same in both induction motors
- None of the above
Correct answer: 2. Slip ring induction motor
Explanation: The slip ring induction motor has a wound rotor with external resistance connected through slip rings and brushes. This design allows for better control over starting torque by varying the resistance in the rotor circuit. Consequently, slip ring induction motors can achieve higher starting torque compared to squirrel cage motors.
