How is the number of armature slots associated with the cost factor?(a

1.	How is the number of armature slots associated with the cost factor?(a) small number of slots leads to less cost(b) small number of slots leads to high cost(c) large number of slots leads to high cost(d) large number of slots leads to low costI have been asked this question during an interview for a job.This intriguing question originated from Armature Design topic in division Design of Synchronous Machines of Design of Electrical Machines
Answer» Right option is (a) small NUMBER of slots leads to less cost The best explanation: The smaller the number of slots, the less will be the cost. This is because there are FEWER coils to WIND, FORM insulate, PLACE into slots, and connect.
