Which of the following single-phase induction motors is generally used in time phonographs?
A. Resistance start
B. Capacitor start capacitor run
C. Shaded pole
D. Universal
Answer: Option C
Solution(By Examveda Team)
Shaded pole motors are commonly used in applications like time phonographs due to their simple construction and reliable operation.They have low starting torque, which is suitable for devices that require consistent and low-speed operation.
These motors are also inexpensive and have a long lifespan, making them ideal for such applications.
