It will perhaps interest you to know that we have rewound a Lucas lighting dynamo armature using less copper in the winding, viz. shorter coils. We have tested this in various ways and in various carcases. Having first tested a dynamo and noted results we have replaced its armature with the one we have wound; in every case we have obtained better results. I attach a list of the tests. The armature rewound was No.1646. E.J.Brock EFC. I think you have the dynamo. I would like your remarks. BY.{R.W. Bailey - Chief Engineer} | ||
