For a wave wounded machine number of brushes for small, large machines

1.	For a wave wounded machine number of brushes for small, large machines respectively is _________________(a) 2, 2(b) 4, 2(c) 2, P(d) Both values depend on the given conditionsThis question was posed to me during an interview for a job.The above asked question is from Wave Winding in portion Armature Windings of DC Machines
Answer» Correct choice is (c) 2, P The best explanation: For a small wave wounded machine number of PARALLEL PATHS are 2, thus 2 brushes are USED. For a large machine total number of brushes is EQUAL to the total number of poles. The spacing between adjacent brushes is C/P commutator segments.
