In a shaded pole motor, the shading coil usually consist of___________?
Correct answer: B. a single turn of heavy copper wire which is short-circuited and carries only induced current
- A. a single turn of heavy wire which is in parallel with running winding
- B. a single turn of heavy copper wire which is short-circuited and carries only induced current
- C. a multilayer fine gauge copper wire in parallel with running winding
- D. none of the above
Explanation
A shading coil is a single-turn thick copper ring that is short-circuited, so its current is produced by electromagnetic induction. It is not connected in parallel with the main winding.
