| 86142 E.{Mr Elliott - Chief Engineer} From Hs{Lord Ernest Hives - Chair}/Wst. c. to BY/RD. c. to Wor.{Arthur Wormald - General Works Manager} Hs{Lord Ernest Hives - Chair}/Wst.5/MA.29.9.33. 40/50 AND BENSPORT DYNAMO. We want to try the experiment of a 40/50 dynamo with an armature wound with 6 turns per coil of 17 S.W.G. wire with the core built up of stamped slotted plates using Baldwins grade 4 material. This experiment is urgent as we want to supersede the existing Bensport & 40/50 dynamo as soon as possible in view of its poor high speed performance. If you are in agreement will you please arrange for an armature to be schemed out and instructed for our bench test. Hs{Lord Ernest Hives - Chair}/Wst. | ||
