In a shaded pole single-phase motor, the revolving field is produced by the use of_________?
Correct answer: D. shading coils
- A. inductor
- B. capacitor
- C. resistor
- D. shading coils
Explanation
Shading coils are short-circuited copper rings placed around part of each pole. Their induced current creates a phase-shifted flux, producing the weak revolving field needed for starting.
