Both these other machines are of course single field winding third brush controlled, we feel that the U.S.A. Bosch, although not well made to external appearances, is nevertheless good electromagnetically. It will be noted that in each case, the carcase thickness is a good deal greater than we have on the Goshawk(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)). EFC. {E. Fowler Clarke - Electrical Engineer} Output performances of one of the latest production Goshawk(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)) dynamos are today being taken and so far the results appear to be an improvement. | ||
