| To EFC. from R.{Sir Henry Royce} COPY to CJ. Bn.{W.O. Bentley / Mr Barrington} X.3533 R1/G16.4.20. X.3533, RE DYNAMO FOR "GOSHAWK". We must have dynamos which are silent and efficient as regards heating. I feel sure we shall get the best results with one coil per slot, and probably a double row of wires and the less deep grooves. Calculate what you think best and let Mr. Day set the armature out for you and send it to me. R.{Sir Henry Royce} | ||
