| To: Rm. {William Robotham - Chief Engineer} Copy to Rs {Sir Henry Royce's Secretary} /Rd, ------------ 1142 Lr {Mr Ellor} /Wst.7/DT. 15.5.40. CAR DYNAMOS. I have recently seen an article in the 'Electrical Times' dated March 14th, describing a new form of constant current generator. It seems to me that this scheme will be well worth trying out on motor car generators, as it would appear to overcome the difficulty experienced with the old third brush dynamo where the "cutting-in" speed was high. Perhaps Rc {R. Childs} might like to get hold of this article and investigate the scheme. Lr {Mr Ellor} /Wst. | ||
