| TO BY.{R.W. Bailey - Chief Engineer} BPC. FROM AJS. C. to -DJ- HS.{Lord Ernest Hives - Chair} X7625 Hs{Lord Ernest Hives - Chair} AJS3/M11.1.27. RECEIVED JAN 12 1927 PHANTOM STARTER MOTOR - 13.1 REDUCTION. We send herewith (to BY.{R.W. Bailey - Chief Engineer}) LeC. 2365. - Main Field Windings of above. We have found that .250 additional length is required on carcase, but if this can be reduced by squeezing the windings together will you please see that it is carried out this way. We understand our winder in Derby has suggested that the thick section main conductor could be split to facilitate winding. We should be glad if you would set this out for the Exp. Dept., using not less than the same area of copper, and same connections as shewn on LeC. 2365. AJS. | ||
