WST New Shunt Dynamo for Peregrine, Japan and Bensport - to D.Sch.546. Referring to your memo Hs{Lord Ernest Hives - Chair}/Wst.2/MA.17.12.32, we should be interested to see the outputs you have obtained compared with our standard third brush machine, which gives 11½ amperes at 14 volts. Regarding paragraph "one" setting out the experimental modifications. Should not the reluctance as a whole remain the same - that is to say - the decrease in the armature reluctance is balanced by the longer pole pieces. E.{Mr Elliott - Chief Engineer} | ||
