| X7625B BY/RD3/E.11.7.28. RHC.{R. H. Coverley - Production Engineer} c. EFC. ----------- STARTER MOTOR CHASSIS 9-EX. --------------------------- We recently instructed a set of Field Windings for the above motor having 6 1/4 turns per pole. This has now been tried and found unsatisfactory, and we think that we can get in the same space a larger section of wire, therefore, will you please make up one set of Field Coils to Drawing D.71626, but using a wire 5/32 x 3/32 which we recently requested you to order in our memo reference BY/RD5/ML.28.6.28. This heavier section wire we hope will give us better results. BY/RD. | ||
