There appear, however, to be certain points in connection with the Dynamo which have not been satisfactory, namely, the one piece cast iron pole shoes. It seems essential that these should be changed over to shoes of the built up type, but whatever modifications are called for in getting EAC.1. Dynamo correct, we shall be in a position to adopt it on the 40/50 by arranging it with a belt drive, immediately on standardisation. BY.{R.W. Bailey - Chief Engineer} P.S. Mild steel shoes of the same dimensions and of one piece formation are being tested out. If, however, these are unsatisfactory it would mean that the design of the pole shoe and the riveting would have to be considered in view of trying to maintain the large radius at the end, otherwise two of the field windings will foul the three terminals at one end unless the carcase is lengthened. | ||
