| X3720 To E. {Mr Elliott - Chief Engineer} from EFC {E. Fowler Clarke - Electrical Engineer} 1 c. to Da. {Bernard Day - Chassis Design} c. to RHC. {R. H. Coverley - Production Engineer} c. to By {R.W. Bailey - Chief Engineer} /Mr. Robinson. EFC {E. Fowler Clarke - Electrical Engineer} 1/T24.1.21. X.3945. - BRUSH SYSTEM -> DYNAMO. X.3526. X.3348. - BRUSH SYSTEM - MOTOR. X.3534. Perhaps you would kindly take up with Mr. Royce sometime just what models of armature windings, field coil windings and brushes he would require for inspection. (1) On the R.R. dynamo made from starter motor parts, there are two armature windings and one field winding. (2) Likewise on the Goshawk(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)) dynamo there are two armature windings and one field winding. (3) On the Goshawk(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)) motor there are two field windings and one armature winding. X.3886. X.3720. All the above are being experimentally instructed. (4) Regarding brush holders - those for the experimental U.S.A. starter motor and for the Goshawk(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)) dynamo and motor are similar in design to one another (though different in dimensions) and similar to the holder depicted on LeC.1193. For the R.R. dynamo made from starter motor parts there is at present instructed the standard type of brush holder as used on the starter motor, but we think perhaps Mr. Royce would like this also to be of the modified type to LeC.1193.
