Which of the following motors is inherently self starting ?
Correct answer: B. Shaded-pole motor
- A. Split motor
- B. Shaded-pole motor
- C. Reluctance motor
- D. None of these
Explanation
A shaded-pole motor is inherently self-starting because the shading coil creates a weak sweeping magnetic field across each pole. Ordinary split-phase motors also require a starting arrangement, but the option names the shaded-pole motor directly.
