REF: Hs{Lord Ernest Hives - Chair}/Wst.6/AD. December 7th, 1931. Messrs. Rolls-Royce Limited, D E R B Y. Dear Sirs, RE: BOSCH DYNAMO. In reply to your letter of the 4th inst; regarding a 150w. Bosch Dynamo, we are enclosing drawings No. AMD60 and AMD 19 which illustrate our nearest standard dynamos to the output mentioned. The RL dynamo which is the type which you now have on test is supplied with standard outputs of 130w. and 180 w. The sample machine recently delivered to you was the 180w. machine arranged to give a 200w. output as specified by you. Our nearest standard machine for your present requirements would be the 130w. dynamo. We should like to know if this output would meet your requirements, but if not we could doubtless arrange with our works to increase this to 150w. should you require this. The RK dynamo also has an output of 130w. but this machine is of considerably smaller dimensions than the RL pattern. Kindly inform us as early as possible if you wish us to supply you with one of these dynamos. Yours faithfully, BOSCH LIMITED. TECHNICAL DEPARTMENT. ENCL: 7928 H.J.G. 5m.II.31 | ||
