A frog leg winding is used in a DC machine to eliminate
A. the use of compensating winding.
B. the use equalizer in lap winding.
C. the use drum winding.
D. reactance voltage produced due to communication.
Answer: B
Share your understanding of this question with the correct explanation.
The correct answer is B. The use of equalizer in lap winding.
A frog-leg winding, also known as a modified lap winding, is used in DC machines to eliminate the need for an equalizer connection. In a lap winding, the equalizer connection is required to maintain the balance of currents in parallel paths of the armature. However, in a frog-leg winding, the arrangement of the winding coils eliminates the need for an equalizer connection. This simplifies the winding design and reduces the complexity of the winding connections.
