Referring to the 3 armatures you are building with 28 slots, after the test of the first one we find that the end connections require moving one commutator bar round to the left looking on the commutator end i.e. retarding the brushes. Will you please have this armature altered as soon as possible and connect the other two up accordingly. First altered, second and third to drawing 87Cg BY {R.W. Bailey - Chief Engineer} /RD. | ||
