| X 8620 To EFC. BY/RD/ML/15.9.24. X.8620 - E.A.C. STARTER MOTOR POLES. We shall be pleased if you can confirm that the size of Pole - D.70327 for the Starter Motor is now correct, so that we may be able to put in hand the tools for the forgings in Ubas Steel. Also we notice that in your calculations - EFC4/T19.6.23, you allow for 4½ turns per pole of main winding, in LeC.1770 21.9.23. W.W. instruct 5½ turns. We assume this is quite O.K. and have instructed the Works accordingly. BY/RD. | ||
