X.8660. R.R. EAC. DYNAMO. X8781d

Please find attached copy of Version 1 - Specification of Production Inspection and Test of the up-to-date R.R. EAC. dynamo fitted with armature with two coils per slot.

It is probable that this will be subject to slight modification at a later date, when complete experimental performance tests of the machines have been made. A second issue of this will be entitled Version 2.

A new Version on the same lines as the above but for the R.R. 20 HP. dynamo with 57 coil armature is in preparation and will supersede the Version dated 15.12.24 already issued under cover of our EFC3/T15.12.24.
