151. If a DC generator was disassembled during overhaul, it is important that the brush holder rigging be installed in the neutral plane. On larger machines, if the brush rigging and end bells are not match-marked, what is the correct procedure for determining the neutral setting using factory marks?

Question

Accepted Answer

with the marked armature slots positioned directly under the center of the interpoles, the brushing rigging should be adjusted and clamped so that the brushes are positioned directly over the marked armature bars.
