Editor's Notes

"Dynamo Machine. Laws." "The best machine is that which with the least amount of energy consumed on the magnets will give the greatest E.M.F. on the smallest resistance in the armature so long as the spark on the commutator may be kept under." List of "unavoidable losses" of energy. Depreciation on commutator, belt, etc. "Magnetic retardation may be largely avoided by using very soft iron." Notes on dimensions & winding of armature. Fr28 notes on "new machine:" armature resistance, heat radiation. Resistance of hypothetical machine 2 times the present bore. Dimensions & calcs for large machine.
