Final answer:
Insufficient information is given to determine the winding type or the number of coils needed for the DC machines. Specific machine requirements and configurations are needed to provide an answer.
Step-by-step explanation:
The student's question doesn't provide enough information to determine the type of armature winding or the number of coils required for both DC machines. To answer this type of question, additional details such as the voltage and current requirements of each machine, the connection method of the coils (series or parallel), and specific machine configurations are necessary. Without these specifics, we cannot accurately calculate the winding type or coil count.
