1.	What is the function of the bands when they are distributed along the axial length of armature?(a) used to reduce the centrifugal forces(b) used to increase the centrifugal forces(c) used to decrease the centrifugal forces(d) used to withstand the centrifugal forcesThe question was asked at a job interview.My question is based upon Bracing of Rotor Windings topic in division Aspects of Design of Mechanical Parts of Design of Electrical Machines
Answer» Right choice is (d) used to withstand the centrifugal forces To explain: The bands are distributed along the AXIAL LENGTH of the ARMATURE and they withstand the centrifugal forces. The centrifugal forces are DUE to the WEIGHT of both the active and inactive parts of armature.
