Electrical Engineering XYZ MCQs
Which of the following motors has low ratings only:
- Capacitor run
- Shaded pole
- Resistance split phase
- Capacitor start
Correct answer: 2. Shaded pole
Explanation: Shaded pole motors are typically used in applications that require low power and have low ratings due to their simple construction and low cost. They are generally less efficient and have lower torque capabilities compared to other types of single-phase motors like capacitor start, capacitor run, and resistance split phase motors. These other motor types are available in a wider range of power ratings and are designed for higher performance applications.
