| To RHC.{R. H. Coverley - Production Engineer} 7614^2 Ha/Wst.2/JH.17.8.36. EXPERIMENTAL PHANTOM III DYNAMO WITH 72 COIL ARMATURE. In connection with our experiments on the above machine, will you please arrange for a second armature to be built. This armature, like the first, should be built in accordance with R.R.Sch.911, but with one difference that it must be wound with 2 turns per coil, instead of 3 turns. It will, therefore, have 8 conductors per slot, instead of 12. Completed Hs{Lord Ernest Hives - Chair}/Wst. | ||
