Question
Download Solution PDFA 6 pole dc armature has simplex lap connected 720 conductors, 3 turns per coil and 4 coil sides per slot. Determine the number of slots in the armature and state whether equalizers can be employed or not?
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFNo of coil sides = 2 × no of coils = 2 × 120 = 240
No of slots = 240/4 = 60 slots
For employing equaliser ring equipotential pitch value should be integer i.e. 2C/P should be integer.
C = Number of coils
P = Number of poles
Hence equaliser rings can be employed.
