Electrical Engineering XYZ MCQs
Equalizer rings are used in case of which winding:
- Wave winding
- Lap winding
- Both of these
- None of these
Correct answer: 2. Lap winding
Explanation: Equalizer rings are used in the case of Lap winding.
Lap winding is a type of armature winding in which the winding is distributed over a number of coils. In lap winding, the end of one coil is connected to the beginning of the adjacent coil, forming a closed loop. The equalizer rings are used to provide additional connections between the coils to ensure that the current is distributed evenly among them. This helps in minimizing the circulating current and prevents unequal loading of the coils in the winding.
In contrast, wave winding is another type of armature winding in which the coils are connected in series, forming a wave-like pattern. Wave winding does not typically use equalizer rings.
