Electrical Engineering XYZ MCQs
In case of high current and low voltage rating which winding is employed to DC machine:
- Lap winding
- Wave winding
- Both of these
- None of these
Correct answer: 2. Wave winding
Explanation: In wave winding, each coil spans only one commutator segment, and the coils are connected in series. Wave winding is generally suitable for machines with low current and high voltage ratings. It results in a winding configuration where the current flows through one coil and then jumps to the next coil, forming a “wave” pattern.
